It’s been a while since I did a number factoid.

My only excuse is the time it takes to compile these, which I haven’t managed to find for a few months, so if you missed them my apologies.

However, there is one today, so if you like this sort of thing I hope you enjoy.

In militaria

• B-25 Mitchell
• Named in honor of General Billy Mitchell, a pioneer of U.S. military aviation, the B-25 Mitchell was an American twin-engined medium bomber manufactured by North American Aviation that saw service over four decades. By the end of its production, nearly 10,000 B-25s in numerous models had been built.
• It was used by many Allied air forces, in every theater of World War II, as well as many other air forces after the war ended, including The Royal Air Force (RAF), Royal Canadian Air Force, Royal Australian Air Force, Dutch Air Force, Soviet Air Force, China Air Force, Brazilian Air Force,  and by the Free French.

• However, the incident for which the B-25 is perhaps best known is one that happened in America. At 9:40 on Saturday, 28 July 1945, a USAAF B-25D crashed in thick fog into the north side of the Empire State Building between the 79th and 80th floors.
• Fourteen people died – eleven in the building and the three occupants of the aircraft including the pilot, Colonel William Smith.
• Betty Lou Oliver, an elevator attendant, survived the impact and a subsequent uncontrolled descent in the elevator.
• Partly as a result of this incident, Towers 1 and 2 of the World Trade Center were designed to withstand an aircraft impact. However, this design was based on an impact by a Boeing 707 aircraft in common use in the late 1960s and early 1970s, not the larger Boeing 767, two of which, (American Airlines Flight 11 and United Airlines Flight 175), struck the towers on September 11, 2001, resulting in their eventual collapse.

.

• Boeing VC-25
• The Boeing VC-25 is the United States Air Force designation for a military version of the Boeing 747 airliner. The A-model (VC-25A) is the only variant of the VC-25.
• The VC-25 is most famous for its role as Air Force One, the call sign of any U.S. Air Force aircraft carrying the President of the United States. The two aircraft currently in U.S. service are highly modified versions of Boeing’s 747-200B, with tail numbers 28000 and 29000.
• Although the Air Force One designation technically applies to the aircraft only while the President is aboard, the term is commonly applied to the VC-25s more generally.
• They often operate in conjunction with Marine One helicopters that ferry the President to airports in circumstances where a vehicle motorcade would be inappropriate.

.

• MIG-25
• The Mikoyan-Gurevich MiG-25 is a supersonic interceptor and reconnaissance aircraft that was among the fastest military aircraft to enter service.
• It was designed by the Soviet Union’s Mikoyan-Gurevich bureau. The first prototype flew in 1964, and the aircraft entered into service in 1970.
• It has a top speed of Mach 2.83 (as high as Mach 3.2, but at risk of significant damage to the engines), and features a powerful radar and four air-to-air missiles.
• When first seen in reconnaissance photography, the large wing planform suggested an enormous and highly maneuverable fighter. This was during a period of time when U.S. design theories were also evolving towards higher maneuverability due to combat performance in the Vietnam War.
• The capabilities of the MiG-25 were better understood in 1976 when Soviet pilot Viktor Belenko defected in a MiG-25 to the United States via Japan. It turned out that the weight of the aircraft necessitated large wings.
• Production of the MiG-25 series ended in 1984 after completion of 1,190 aircraft. A symbol of the Cold War, the MiG-25 flew with Soviet allies and former Soviet republics, remaining in limited service in Russia and several other nations.
• It is the second fastest and second highest-flying military aircraft ever fielded after the SR-71 reconnaissance aircraft.

.

• USS Terry (DD-25)
• Launched on 21 August 1909 and commissioned on 18 October 1910, the USS Terry (DD-25) was a modified Paulding-class destroyer in the United States Navy during World War I, and later in the United States Coast Guard, designated CG-19. She was the first ship named for Edward Terry.

• She remained there until she was transferred to the Coast Guard on 7 June 1924. Based in New York, she served as part of the Rum Patrol, until 18 October 1930, when she was returned to the Navy and restored on the Navy list in a decommissioned status, listed as a “vessel to be disposed of by sale or salvage.” On 2 May 1934, Terry was sold for scrapping. Her name was struck from the Naval Vessel Register on 28 June 1934.

• Copeland was launched on 26 July 1980, and commissioned on 7 August 1982.
• Decommissioned and stricken on 18 September 1996, she was transferred to Egypt the same day as Mubarak (F911). After the 2011 revolution the ship was renamed to remove the former ruler’s name. The ship is currenty named Alexandria (F911) and remains in active service with the Egyptian Navy.

• In 1982 she won the Marjorie Sterrett Battleship Fund Award.
• After receiving her final nuclear refueling overhaul in 1983–85, Bainbridge operations included counter-drug smuggling patrols in the Caribbean, several deployments to northern European waters and four Mediterranean cruises including combat operations off Libya.
• During 1994 she was deployed to support UN resolutions that became part of Operation Sharp Guard, enforcing sanctions against the Former Republic of Yugoslavia and Bosnia.
• Finally deactivated in October 1995, Bainbridge was decommissioned in September 1996 and towed to Bremerton, Washington in mid-1997 where she was put in dry dock to begin “recycling,” the process by which nuclear-powered warships are scrapped.

.

• USS Somerset (LPD-25)
• The USS Somerset (LPD-25), a San Antonio-class amphibious transport dock, is the fifth ship of the United States Navy of that name; in this case in honor of Somerset County, Pennsylvania.
• The name honors the passengers of United Airlines Flight 93 whose actions prevented terrorist hijackers from reaching their intended target, forcing the airplane to crash in Stonycreek Township in Somerset County, PA, on September 11, 2001. In the words of Secretary of the Navy Gordon R. England, “The courage and heroism of the people aboard the flight will never be forgotten and USS Somerset will leave a legacy that will never be forgotten by those wishing to do harm to this country.”
• Some 22 tons of steel from a crane that stood near Flight 93’s crash site have been used to construct Somerset’s stemhold.
• She was launched on 14 April 2012, and was christened three months later, on 28 July.

.

• HMS Medway
• HMS Medway was the first purpose-built submarine depot ship constructed for the Royal Navy. She was built by Vickers Armstrong at Barrow-in-Furness during the late 1920s. The ship served on the China Station before the Second World War and was transferred to Egypt in early 1940.
• Ordered to evacuate Alexandria in the face of the German advance after the Battle of Gazala in May 1942, Medway sailed for Lebanon at the end of June, escorted by a light cruiser and seven destroyers.
• Despite her strong escort, she was torpedoed and sunk by a German submarine on 30 June.

.

• HMS Warwick (D-25)

The vehicle had a crew of five, a weight of 35,100 kg, used the same 474 hp, GAN V8 engine as the earlier T23, and had a top speed of 48 km/h.
• The T25 was developed with a variant which itself was virtually the same, the only difference was that the T25 was built with horizontal volute spring suspension, and the variant T25E1 had the torsion bar suspension later adopted for use in the M26. Only 40 T25 and T25E1 prototypes were built.

.

• M25 “Three Shot Bazooka”
• Bazooka is the common name for a man-portable recoilless antitank rocket launcher weapon, widely fielded by the United States Army. Also referred to as the “Stovepipe”, the innovative bazooka was among the first-generation of rocket propelled anti-tank weapons used in infantry combat.
• Featuring a solid rocket motor for propulsion, it allowed for high-explosive anti-tank (HEAT) warheads to be delivered against armored vehicles, machine gun nests, and fortified bunkers at ranges beyond that of a standard thrown grenade or mine. The Bazooka also fired a HESH round, effective against buildings and tank armour.
• The universally-applied nickname arose from the M1 variant’s vague resemblance to the musical instrument called a “bazooka” invented and popularized by 1930s U.S. comedian Bob Burns.
• The M25 “Three Shot Bazooka” was an experimental tripod mounted rocket launcher with overhead magazine circa 1955.

• The upper and lower receivers are made from aluminum forgings, and the handguard is turned aluminum, all impervious to the weather; climate changes will have no effect on accuracy or bedding.
• Additionally, the R-25 has a Mossy Oak Treestand coating, so if you aren’t careful in the woods, you may spend some time hunting for the rifle you set down while doing something else.
• The magazine holds four rounds, a prudent choice since the purpose of the R-25 is hunting.

In politics

• 21^st President of the United States
• Chester Alan Arthur (October 5, 1829 – November 18, 1886) was the 21st President of the United States (1881–85). He became President after the assassination of President James A. Garfield.
• Born in Fairfield, Vermont, Arthur grew up in upstate New York and practiced law in New York City. He devoted much of his time to Republican politics and quickly rose in the political machine run by New York Senator Roscoe Conkling.
• Appointed by President Ulysses S. Grant to the lucrative and politically powerful post of Collector of the Port of New York in 1871, Arthur was an important supporter of Conkling and the Stalwart faction of the Republican Party.
• In 1878 the new president, Rutherford B. Hayes, fired Arthur as part of a plan to reform the federal patronage system in New York. When James Garfield won the Republican nomination for President in 1880, Arthur was nominated for Vice President to balance the ticket by adding an eastern Stalwart to it.
• After just half a year as vice president, Garfield was assassinated and Arthur unexpectedly became the 21st President of the united states.
• To the surprise of reformers, Arthur took up the reform cause that had once led to his expulsion from office. He signed the Pendleton Act into law, and enforced its provisions vigorously.
• Suffering from poor health, Arthur made only a limited effort to secure renomination in 1884; he retired at the close of his term. As journalist Alexander McClure would later write, “No man ever entered the Presidency so profoundly and widely distrusted as Chester Alan Arthur, and no one ever retired … more generally respected, alike by political friend and foe.”

• Ghost Ship 21
• A ghost ship, also known as a phantom ship, is a ship with no living crew aboard. It may be a ghostly vessel in folklore or fiction, such as the Flying Dutchman, or a real derelict found adrift with its crew missing or dead, like the Mary Celeste. The term is sometimes also used for ships that have been decommissioned but not yet scrapped.
• There have been many examples throughout history, for example,
• Undated: The Caleuche is a mythical ghost ship which, according to local folklore and Chilota mythology, sails the seas around Chiloé Island, Chile, at night.
• 1738 onwards: The Palatine Light, a ship who lost half her crew running aground off Rhode Island, possibly being lured there and pillaged by the locals. Said to appear every December.
• 1748 onwards: The Lady Lovibond is said to have been deliberately wrecked on Goodwin Sands on 13 February and to reappear off the Kent coast every fifty years.
• 1786 onwards: The Ghost Ship of Northumberland Strait, a burning ship seen regularly between Prince Edward Island and New Brunswick.
• 1795 onwards: The Flying Dutchman, a ship manned by a captain condemned to eternally sail the seas, has long been the principal ghost ship legend among mariners and has inspired several works.
• 1813 onwards: After the American schooner Young Teazer was sunk in an explosion during the War of 1812, a burning apparition known as the “Teazer Light” has been reported off Maine.
• 1858 onwards: The Eliza Battle, a paddle steamer that burned in 1858 on the Tombigbee River in Alabama, is purported to reappear, fully aflame, on cold and windy winter nights to foretell of impending disaster.
• 1878 onwards: An apparition has been reported where the HMS Eurydice sank off the Isle of Wight. Witnesses include a Royal Navy submarine in the 1930s and Prince Edward, Earl of Wessex, in 1998.
• 1872 or 1882: The Iron Mountain riverboat, according to legend, mysteriously disappeared while travelling the Mississippi River and left the barges it was towing adrift. In reality, the ship sank in 1882 near Vicksburg after running aground, and its fate was never mysterious.
• 1928: The København was last heard from on December 28, 1928. For two years following its disappearance sightings of a mysterious five-masted ship fitting its description were reported in the Pacific Ocean.
• Historically attested
• 1855: HMS Resolute was discovered drifting off the coast of Baffin Island. It had been one of four vessels from Edward Belcher’s search expedition for John Franklin that had been abandoned the previous year when it was trapped in pack ice in Viscount Melville Sound. The ship drifted some 1,200 miles (1,900 km) before it was found, freed from the ice.
• 1872: Amazon (later renamed Mary Celeste). In 1872 the Mary Celeste, perhaps the most historically famous derelict, was found abandoned between mainland Portugal and the Azores archipelago. It was devoid of all crew, but largely intact and under sail, heading toward the Strait of Gibraltar. While Arthur Conan Doyle’s story “J. Habakuk Jephson’s Statement” based on this ship added some strange phenomena to the tale (such as that the tea found in the mess hall was still hot), the fact remained that the last log entry was 11 days prior to the discovery of the ship.
• 1884: In 1884 the Resolven was found abandoned between Baccalieu Island and Catalina, Newfoundland and Labrador, with its lifeboat missing. Other than a broken yard, it had suffered minimal damage. A large iceberg was sighted nearby. It has been claimed that none of the seven crew members or four passengers were accustomed to northern waters and it was suggested that they panicked when the ship was damaged by ice,[9] launched the lifeboat, and swamped, though no bodies were found. Three years later, Resolven was wrecked while returning to Newfoundland from Nova Scotia with a load of lumber.
• 1917: Zebrina, a sailing barge, departed Falmouth, England, with a cargo of Swansea coal bound for Saint-Brieuc, France. Two days later she was discovered aground on Rozel Point, south of Cherbourg, without damage except for some disarrangement of her rigging, but with her crew missing.
• 1921: The Carroll A. Deering, a five-masted cargo schooner, was found stranded on a beach on Diamond Shoals, North Carolina. The ship’s final voyage had been the subject of much debate and controversy, and was investigated by six departments of the US government, largely because it was one of dozens of ships that sank or went missing within a relatively short period of time. While paranormal explanations have been advanced, the theories of mutiny or piracy are considered more likely.
• 1931: The Baychimo was abandoned in the Arctic Ocean when it became trapped in pack ice and was thought doomed to sink, but remained afloat and was sighted numerous times over the next 38 years without ever being salvaged.
• 1933: A lifeboat from the 1906 wreck of the passenger steamship SS Valencia off the southwest coast of Vancouver Island was found floating in the area in remarkably good condition 27 years after the sinking. Sailors have also reported seeing the ship itself in the area in the years following the sinking, often as an apparition that followed down the coast.
• 1955: The MV Joyita was discovered abandoned in the Pacific. A subsequent inquiry found the vessel was in a poor state of repair, but determined the fate of passengers and crew to be “inexplicable on the evidence submitted at the inquiry”.
• 1959: A ghost submarine was found floating without a crew in the Bay of Biscay off northern Spain. It was later discovered that the empty sub was being towed by another vessel and the chain had snapped.
• 1969: The Teignmouth Electron was found adrift and unoccupied in the Atlantic Ocean. Investigation led to the conclusion that its sole crewmember, Donald Crowhurst, had suffered a psychiatric breakdown while competing in a solo around-the-world race and committed suicide by jumping overboard.
• 2003: The High Aim 6 was found drifting in Australian waters, 80 nautical miles (150 km; 92 mi) east of Rowley Shoals, with its crew missing. The derelict was subsequently scuttled.
• 2006: The tanker Jian Seng was found off the coast of Weipa, Queensland Australia in March. Its origin or owner could not be determined, and its engines had been inoperable for some time.
• 2006: In August the “Bel Amica” was discovered off the coast of Sardinia. The Coast Guard crew that discovered the ship found half eaten Egyptian meals, French maps of North African seas, and a flag of Luxembourg on board.
• 2007: A 12-metre catamaran, the Kaz II, was discovered unmanned off the coast of Queensland, northeast Australia in April.[18] The yacht, which had left Airlie Beach on Sunday 15 April, was spotted about 80 nautical miles (150 km) off Townsville, near the outer Great Barrier Reef on the following Wednesday. When boarded on Friday, the engine was running, a laptop was running, the radio and GPS were working and a meal was set to eat, but the three-man crew were not on board. All the sails were up but one was badly shredded, while three life jackets and survival equipment, including an emergency beacon, were found on board. A search for the crew was abandoned on Sunday 22nd as it was considered unlikely that anyone could have survived for that period of time.
• 2008: The abandoned 50 ton Taiwanese fishing vessel Tai Ching 21 was found drifting near Kiribati on 9 November. The ship had suffered a fire several days previously, and its lifeboat and three life rafts were missing. No mayday call was received, and the ship had last been heard from on 28 October. A search of 21,000 square miles (54,000 square km) of the Pacific Ocean north of Fiji by a US Air Force C-130 Hercules and a New Zealand Air Force P-3 Orion found no trace of the Taiwanese captain or crew (18 Chinese, 6 Indonesians, and 4 Filipinos).
• 2012: The Ryou-Un Maru, a Japanese fishing vessel swept away by the March 2011 tsunami, was found floating adrift towards Canada after nearly a year at sea, no crew believed to be on board. The vessel was sunk on April 5, 2012 by the United States Coast Guard.

In militaria

• Mig-21
• The Mikoyan-Gurevich MiG-21 is a supersonic jet fighter aircraft, designed by the Mikoyan-Gurevich Design Bureau in the Soviet Union. It was popularly nicknamed “balalaika”, from the aircraft’s planform-view resemblance to the Russian stringed musical instrument or olówek (English: pencil) by Polish pilots due to the shape of its fuselage.
• Early versions are considered second-generation jet fighters, while later versions are considered to be third-generation jet fighters.
• Some 50 countries over four continents have flown the MiG-21, and it still serves many nations a half-century after its maiden flight. The fighter made aviation records. At least by name, it is the most-produced supersonic jet aircraft in aviation history and the most-produced combat aircraft since the Korean War, and it had the longest production run of a combat aircraft (1959 to 1985 over all variants).

.

• IAI Kfir F-21
• The Israel Aircraft Industries Kfir F-21 is an Israeli-built all-weather, multirole combat aircraft based on a modified French Dassault Mirage 5 airframe, with Israeli avionics and an Israeli-made version of the General Electric J79 turbojet engine.
• The Kfir entered service with the IAF in 1975, the first units being assigned to the 101st “First Fighter” Squadron. Over the following years, several other squadrons were also equipped with the new aircraft. The role of the Kfir as the IAF’s primary air superiority asset was short-lived, as the first F-15 Eagle fighters from the United States were delivered to Israel in 1976.
• The Kfir’s first recorded combat action took place on November 9, 1977, during an Israeli air strike on a training camp at Tel Azia, in Lebanon. The only air victory claimed by a Kfir during its service with the IAF occurred on June 27, 1979 when a Kfir C.2 shot down a Syrian MiG-21.
• Twenty-five modified Kfir C.1s were leased to the US Navy and the US Marine Corps from 1985 to 1989, to act as adversary aircraft in dissimilar air combat training (DACT). These aircraft, designated F-21A Kfir, had narrow-span canard foreplanes and a single small rectangular strake on either side of the nose which considerably improved the aircraft’s maneuverability and handling at low speeds.

• Blücher 21 cm/45 (8.27″) SK L/45
• Used afloat only on the Armored Cruiser Blücher which was sunk at the World War I battle of Dogger Bank.  After her sinking, four reserve guns were given to the German Army.
• During World War II these guns were used as coastal artillery.  They were then supplied with a better ballistically shaped shell and with a larger propellant charge for increased range.
• Constructed of a tube, two layers of hoops and a jacket.  Used the Krupp horizontal sliding wedge breech block.  About 16 guns were made.

.

• 21-K
• The 45 mm anti-aircraft gun (21-K) was a Soviet design adapted from the 45 mm anti-tank gun M1937 (53-K). This was a copy of a 3.7 cm (1.5 in) German weapon designed by Rheinmetall that was sold to the Soviets before Hitler came to power in 1933 that had been enlarged to 45 mm (1.8 in) in increase its penetrating power.
• It was used by the Soviet Navy to equip almost all of their ships from 1934 as its primary light anti-aircraft gun until replaced by the fully automatic 37 mm 70-K gun from 1942 to 1943.
• It was used in World War II and during the Cold War as the Soviets exported their World War II-era ships to their friends and allies.
• However it was not very effective as its slow rate of fire and lack of a time fuze required a direct hit to damage targets.

.

• GAU-21 (M3M)
• The M3M was designated by the U.S. Navy as the GAU-21 in 2004 and is currently used by all services within the U.S. Department of Defense (DoD).
• An evolution of the M3 .50-caliber heavy machine gun, it produces a blistering 1,100 rounds per minute cyclic rate of fire through the use of open-bolt operation and a dual recoil buffer system. Operating independent of either electrical or hydraulic power sources, the M3M/GAU-21’s unique soft mount system enhances weapon accuracy and minimizes the firing vibration transmitted to the airframe.
• FN Herstal has been awarded a solesource U.S. Navy contract to produce the M3M .50 caliber machine guns under the Gun, Aircraft, Unit-21 (GAU-21) designation for Navy and Marine Corps rotary-wing assault aircraft.
• The FN GAU-21 (M3M) is a .50 caliber (12.7x99mm) single barrel rapid-fire machine gun suitable for rotary-wing aircraft applications providing defensive firepower ranging out to nearly 2000 meters.

• 21 Series Beretta
• The 21 Series Beretta pocket pistol (Bobcat) has the same dedication to advanced design, uncompromising quality and strict quality control that make the 92F, Cougar and Cheetah such international standouts.
• It has a user-friendly design, exclusive tip-up barrel allowing the user to easily load a round directly into the chamber or assisting in the safe clearing of the pistol by allowing a live round to be easily removed from the chamber and the bore quickly checked. Jamming and stovepiping problems are virtually eliminated by the open slide design shared by all small frame Berettas.
• Chambered for .22LR or .25ACP (6.35 mm), this compact, rugged small frame measures just 4.9 inches (125 mm) overall and weighs only 11.5 ounces (325 grams). It features a lightweight, alloy frame, blued steel slide, tip-up barrel, and double/single action. The Bobcat comes with a 7-round magazine for .22LR ammunition, or an 8 round magazine for .25 (6.35 mm)caliber cartridges.

.

• Twenty-one Gun Salute
• Legend has it that Twenty-one guns are fired in U.S. national military salutes because the digits in 1776 add up to 21. However, despite the fact that the year 1776 is deeply significant to Americans and the total of its digits does add up to 21, the legend is untrue because the custom of the 21-gun salute antedates the American Revolution by at least several decades.
• Also interesting is the fact that, although we now view weaponry salutes as honors proudly bestowed by fighting men upon those of high rank or great achievement, saluting in days long ago was an act of submission; a tangible way of demonstrating that the one performing the action was voluntarily placing himself in the power of the one being saluted. Guns would be emptied a ritual number of times, or sails would be lowered, or spears would be pointed towards the ground, the significance being that those carrying out the act were saying “I yield to your authority, and as proof I’ve just rendered my weapon incapable of being used against you.”
• Over time the practice evolved into a custom honorary and ceremonial as well as practical. Today’s salute is far more a mark of respect than an act of submission.
• Cannons became part of weaponry salutes in the 14th century.  A just-emptied cannon was a useless piece of ordnance and so made a fine visible display of the lack of hostile intent. Warships took to firing honorary seven-gun salutes, with that number likely chosen for its astrological and biblical significance. Because those crewing cannons on land had access to far greater supplies of powder, they were able to fire three guns (a number chosen for its mystical significance) for every shot fired afloat, making the honorary salute by shore batteries 21 guns.
• Eventually, an understanding was reached that the international salute should be established as 21 guns.
• Today, the national salute of 21 guns is fired in honor of a national flag, the sovereign or chief of state of a foreign nation, a member of a reigning royal family, and the President, ex-President, and President-elect of the United States. It is also fired at noon of the day of the funeral of a President, ex-President, or President-elect; Washington’s Birthday; Presidents’ Day; and the Fourth of July. On Memorial Day, a salute of 21 minute guns (i.e., guns discharged at one-minute intervals) is fired at noon while the flag is flown at half staff.
