• 28 is the molecular weight of nitrogen, (N2 = 28.02) and the molecular weight of carbon monoxide, (CO = 12 + 16 = 28.01); also interesting in that while carbon monoxide is poisonous, nitrogen is essential to life, yet they have the same molecular weight of 28 daltons.
• 28 is the fourth magic number in physics.
• The average human menstrual cycle is 28 days although no link has been established with the nightlighting and the Moon.
• Skin research has discovered that the epidermis is constantly regenerating itself, and all of its cells are replaced every 28 days.

• STS-28
• STS-28 was the 30th NASA Space Shuttle mission, and the fourth dedicated to United States Department of Defense purposes. It was also the eighth flight of Space Shuttle Columbia.
• The mission launched on 8 August 1989 and traveled 2.1 million miles during 81 orbits of the Earth, before landing on runway 17 of Edwards Air Force Base, California, on 13 August.
• The mission details of STS-28 are classified, but the payload is widely believed to have been the first SDS-2 communications satellite.
• The crew consisted of Commander Brewster H. Shaw, Jr., Pilot Richard N. Richards, and three Mission Specialists, James C. Adamson, David C. Leestma and Mark N. Brown.

. 

• Space Shuttle Challenger
• One of the worst space related disasters happened on January 28 1986.
• On that fateful day Space Shuttle Challenger (mission STS-51-L) broke apart 73 seconds into its flight, leading to the deaths of its seven crew members.
• The spacecraft disintegrated over the Atlantic Ocean, off the coast of central Florida at 11:38 EST (16:38 UTC). Disintegration of the entire vehicle began after an O-ring seal in its right solid rocket booster (SRB) failed at liftoff. The O-ring failure caused a breach in the SRB joint it sealed, allowing pressurized hot gas from within the solid rocket motor to reach the outside and impinge upon the adjacent SRB attachment hardware and external fuel tank. This led to the separation of the right-hand SRBs aft attachment and the structural failure of the external tank. Aerodynamic forces promptly broke up the orbiter.
• The crew compartment and many other vehicle fragments were eventually recovered from the ocean floor after a lengthy search and recovery operation. Although the exact timing of the death of the crew is unknown, several crew members are known to have survived the initial breakup of the spacecraft. However, the shuttle had no escape system and the impact of the crew compartment with the ocean surface was too violent to be survivable.
• The disaster resulted in a 32-month hiatus in the shuttle program and the formation of the Rogers Commission, a special commission appointed by United States President Ronald Reagan to investigate the accident. The Rogers Commission found NASA’s organizational culture and decision-making processes had been key contributing factors to the accident. NASA managers had known contractor Morton Thiokol’s design of the SRBs contained a potentially catastrophic flaw in the O-rings since 1977, but failed to address it properly. They also disregarded warnings from engineers about the dangers of launching posed by the low temperatures of that morning and had failed to adequately report these technical concerns to their superiors.
• What Rogers did not highlight was the fact the vehicle was never certified to operate in temperatures that low.
• Many viewed the launch live because of the presence of crew member Christa McAuliffe, the first member of the Teacher in Space Project and the (planned) first female teacher in space.
• The Challenger disaster has been used as a case study in many discussions of engineering safety and workplace ethics.

In militaria, shipping and aviation

• T-28 Trojan
• T-28 Trojan is a training military aircraft. In 1948 the U.S. Air Force originally acquired the T-28A as a trainer to replace the venerable AT-6. The T-28B and T-28C were acquired by the U.S. Navy and included a tailhook for carrier landing training. T-28 was shown on Card #15 of Topps Wings: Friend or Foe (1952).

 

.

• Miles M.28 Mercury
• The Miles M.28 Mercury was a British aircraft designed for either training or communications during the Second World War. It was a single-engine, monoplane of wooden construction with a twin tail and a tailwheel undercarriage with retractable main units.
• Originally, the M.28 had been planned as a replacement for the Whitney Straight and Monarch, but this was shelved when war broke out.
• In 1941, the project was revived in response to a requirement for a training and communications aircraft. The design was produced as a private venture by Ray Bournon using Miles’ normal wooden construction. The resulting machine introduced several features not found on trainers ncluding retractable undercarriage and trailing edge flaps. In the communications role, the M.28 had four seats and a range of 500 miles (800 km).
• Owing to Miles’ heavy commitment to war-production, however, only six aircraft were built, of slightly varying specifications, the last being the Mercury 6 which first flew in early 1946.  Examples were operated in the United Kingdom, Germany, Switzerland and Australia.

 .

• XB-28
• The North American XB-28 (NA-63) was an aircraft proposed by the North American Aviation to fill a strong need in the United States Army Air Corps for a high-altitude medium bomber. It never entered into full production, with only two aircraft having been built.

. 

• MiG-28
• The MiG-28 is a fictional aircraft that has appeared in several different unrelated works. These fictional aircraft have been independently created and the aircraft share nothing but a name.
• The first instance of a “MiG-28” was in the 1978 Quiller novel The Sinkiang Executive written by Adam Hall. Referred to in the work as the MiG-28D, it was an aircraft that resembled a somewhat modified MiG-25, but with sharper air intakes and swept wings.
• In the 1986 film Top Gun, Lt. Pete “Maverick” Mitchell (Tom Cruise) squared off against MiG-28s of unspecified nationality. These were actually US Northrop F-5s, which at the time were being used as aggressor aircraft for dissimilar air combat training at the real TOPGUN seminar (now known as the United States Navy Fighter Weapons School). The F-5s “acting” as MiG-28s were painted flat black to indicate their villainous status, and retained those paint jobs after production closed. The paint also increased the aircraft’s visibility, a plus for filmmaking.
• Another MiG-28 is “seen” in the 1988 ABC television series Supercarrier. This MiG-28 was a fictional Soviet stealth fighter. An F-16 fighter in Soviet-style markings was used to “simulate” the Soviet fighter.

• Fokker F-28 Fellowship
• The Fokker F28 Fellowship is a short range jet airliner designed developed in Holland (1964) and assembled by defunct Dutch aircraft manufacturer Fokker. The Fokker F-28 Fellowship jet was to complement Fokker’s highly successful F-27 turboprop.
• Announced by Fokker in April 1962, production was a collaboration between a number of European companies, namely Fokker, MBB of West Germany, Fokker-VFW (also of Germany), and Short Brothers of Northern Ireland. There was also government money invested in the project, with the Dutch government providing 50% of Fokker’s stake and the West German government having 60% of the 35% German stake.
• In total 241 Fokker F-28s were sold, including 160 in commercial service and 10 used as corporate jets.
• The Fokker F-28 shown on a 40¡ Nauru stamp. Postage stamps with Fokker airplanes

. 

• Enstrom F-28
• The Enstrom F-28 and 280 are a family of small, light piston-engined helicopters produced by the Enstrom Helicopter Corporation.[1]
• Since delivering their first helicopter shortly after Federal Aviation Administration type certification of the F-28 model in April 1965, Enstrom helicopter has produced (as of 2007) approx 1,200 aircraft.[2]
• The company produces three models, the F-28, the more aerodynamic 280 and the turbine-engined 480, each with their own variants. The F-28 and 280 both use Lycoming piston engines virtually identical to those found in general aviation fixed-wing aircraft

. 

• T-28 Tank
• The Soviet T-28 multi-turret medium battle tank was among the world’s first medium tanks and became a symbol of the Red Army as was its heavier “brother” the T-35. Its silhouette is well known from pre-war newsreel about Soviet military parades in Moscow’s Red Square.
• 41 T-28 tanks were built in 1933 with hightest production of 131 in 1939. In the summer of 1941, the design of the T-28 became obsolete due to the drawbacks of multi-turret vehicles. The T-28 could hit any German tank from long distances.

 .

• The B28
• The B28, originally Mark 28, was a thermonuclear bomb carried by U.S. tactical fighter bombers and bomber aircraft. From 1962 to 1972 under the NATO nuclear weapons sharing program, American B28s also equipped six Europe-based Canadian CF-104 squadrons known as the RCAF Nuclear Strike Force. It was also supplied for delivery by UK-based Royal Air Force Valiant and Canberra aircraft assigned to NATO under the command of SACEUR. Also USN carrier based attack aircraft such as the A3D Skywarrior and the A4D Skyhawk were equipped with the MK 28.

 .

• HMS Kandahar (F28)
• HMS Kandahar (F28) was a K-class destroyer of the Royal Navy, named after the Afghan city of Kandahar.
• Kandahar was launched on 21 March 1939, and on 21 February 1941, in company with HMS Kimberley and HMS Manchester, she captured the German blockade runner SS Wahehe off Iceland. On 19 December 1941, she was part of British Force K, tasked to intercept an Italian convoy bound for Tripoli when she was irreparably damaged by a newly laid Italian mine whilst attempting to rescue the stricken HMS Neptune. She was scuttled the next day by Jaguar. 73 men went down with the ship.

. 

• HMS Cleopatra (F28)
• HMS Cleopatra (F28) was a Leander-class frigate of the Royal Navy, built at HMNB Devonport. She was launched on 25 March 1964 and commissioned on 4 January 1966.
• Upon Cleopatra’s commissioning, she joined the 2nd Destroyer Squadron, Far East Fleet and then participated in the Beira Patrol, which was designed to prevent oil reaching the landlocked Rhodesia via the then Portuguese colony of Mozambique (Lorenzo Marques).
• In 1969, Cleopatra was present at the Evans-Melbourne collision.
• In 1972, Cleopatra took part in escort duties during the Queen and Duke of Edinburgh’s South East Asia tour.
• In 1973, Cleopatra was dispatched to protect British trawlers against the Icelandic Coast Guard in the Second Cod War.
• Afterwards, Cleopatra began her modernisation, becoming the first Batch Two Leander to do so, which included the removal of her one twin 4.5-in gun to allow the addition of the Exocet anti-ship missile system.
• On 31 January 1992, Cleopatra was decommissioned. The following year, Cleopatra was sold for scrap.

 .

• Mosin–Nagant M/28
• The Mosin–Nagant is a bolt-action, internal magazine-fed, military rifle created under the government commission by Russian inventors, and used by the armed forces of the Russian Empire, the Soviet Union and various other nations.
• It has gone through many variations, the M/28 designed by the White Guard. The M/28 differs from the Army’s M/27 primarily in the barrel band design, which is a single piece compared to the M/27’s hinged band, and an improved trigger design. Barrels for the M/28 were initially purchased from SIG, and later from Tikkakoski and SAKO.
• The M/28-30 is an upgraded version of the M/28. The most noticeable modification is a new rear sight design.

.

• Smith & Wesson (S & W) Model 28
• The most famous handgun with the 28 designation is the Smith & Wesson (S & W) Model 28, also known as the Highway Patrolman. It is an N-frame revolver chambered for the .357 Magnum cartridge, in production from 1954 to 1986. It is a budget version of the S&W Model 27.

• The number of days in the shortest month of the Gregorian calendar, February (except in leap years, when there are twenty-nine).
• The Gregorian calendar follows a 28-year cycle for the most part, since there are seven days in a week and leap year generally occurs every four years; usually, a calendar from any year is the same as that from 28 years earlier (e.g., 2008 and 1980 or 2009 and 2037). However, that rule holds only when there have been exactly seven leap days in a 28-year interval; years divisible by 100 but not by 400 are not leap years. Indeed, 1900 (as well as 2100, 2200, etc.) does not use the same calendar as 1872 (2072, 2172, etc., respectively) for the simple reason that 1900 is not a leap year. In 28 years, any day-of-the-week and date combination occurs exactly four times. February 29 will fall on each day of the week once.
• In Jewish tradition there is a 28 year solar cycle in which the sun returns to its place in Creation every 28 solar years. This is commemorated in April every 28 years with the recitation of Birkat Hachama, the blessing of the sun.

In Religion

• In Japanese culture, the number 42 is considered unlucky because the numerals when pronounced separately — “shi ni” (four two) — sound like the phrase, “unto death”;
• There are 42 principles of Ma’at, the Ancient Egyptian personification of physical and moral law, order, and truth. In the judgement scene described in the Egyptian and the Book of the Coming/Going Forth by Day, there are 42 gods and goddesses of Egypt, personifying the principles of Ma’at. These 42 correspond to the 42 Nomes (Governmental Units) of Egypt. If the departed successfully answers all 42, s/he becomes an Osiris;
• 42 is the number with which God creates the Universe in Kabbalistic tradition; 
• In Judaism, the number (in the Babylonian Talmud, compiled 375 AD to 499 AD) of the “Forty-Two Lettered Name” ascribed to God. Rab (or Rabhs), a 3rd century source in the Talmud stated “The Forty-Two Lettered Name is entrusted only to him who is pious, meek, middle-aged, free from bad temper, sober, and not insistent on his rights”. 
• 42 is a sacred Tibetan number and there is also a 42 armed Hindu God;
• The first book to be printed with movable type, the Gutenberg Bible, is also known as the “42-line Bible”, as the book contained 42 lines per page;
• The Forty-Two Articles (1552), largely the work of Thomas Cranmer, were intended to summarise Anglican doctrine, as it now existed under the reign of Edward VI..

.

In The Bible

• Forty Two, 3½ and 1260 – this is the amount that is given to the wicked or for people to bear fruit. Judgment occurs at the end. It is based on the law that God only expects results after the third year of planting (Leviticus 19: 23-25);
• This time period appears in many prophecies as 1260 days, 42 months or 3½ years. It is the period that God allows the beast to operate. Notice that this is equal to 6 x 7 months. It is man’s portion of the jubilee cycle; 
• Two female bears kill forty two children after they ridiculed the prophet of God. 2 Kings 2: 24; 
• 42 Cities are given to the Levites in addition to six cities of refuge (Numbers 35: 6); 
• 42 men of Beth-azmaveth were counted in the census of men of Israel upon return from exile (Ezra 2:24);

In Science

• 42 is the atomic number of molybdenum;
• 42 is the value of the angle rounded to whole degrees for which a rainbow appears (the critical angle);
• In 1966, mathematician Paul Cooper theorized that the fastest, most efficient way to travel across continents would be to bore a straight hollow tube directly through the Earth, connecting a set of antipodes, evacuate it (remove the air), and then just fall through. The first half of the journey consists of free-fall acceleration, while the second half consists of an exactly equal deceleration. The time for such a journey works out to be 42 minutes. Remarkably, even if the tube does not pass through the exact center of the Earth, the time for a journey powered entirely by gravity (also known as Gravity train) always works out to be 42 minutes, as long as the tube remains friction-free, as while gravity’s force would be lessened, so would the distance traveled at an equal rate. (The same idea was proposed, without calculation by Lewis Carroll in 1893 in Sylvie and Bruno Concluded.)

In Politics

• The 42nd President of the Unites States of America was Democratic Party William (Bill) Jefferson Clinton, from January 20, 1993 to January 20, 2001. Vice President was Al Gore. Remembered more for ‘blow-jobs’ in the White House, Clinton’s Presidency also oversaw the disastrous Gramm-Leach-Bliley Act in 1999, that repealed the parts of the Glass–Steagall Act which had not already been repealed. This 1999 Act took down barriers to competition between traditional banks, investment banks, and insurance companies, in some cases allowing firms to participate in all three markets thus making distinctions between these categories less clear. It has been held largely responsible for the current financial crisis.

In Militaria

• XB-42
• The most notable aircraft with the 42 designation was the XB-42 ‘Mixmaster’. This aircraft was developed initially as a private venture and an unsolicited proposal was presented to the United States Army Air Forces in May 1943 which resulted in an Air Force contract for two prototypes and one static test airframe, the USAAF seeing an intriguing possibility of finding a bomber capable of the Boeing B-29 Superfortress’ range without its size or cost.
• The aircraft was unusual in design in that it had a pair of Allison V-1710-125 liquid-cooled V-12 engines mounted behind the crew’s cabin, each driving one of the twin propellers which protruded from the rear of the aircraft’s fuselage. The pilot and co-pilot sat under twin bubble canopies, and the bombardier sat in the extreme front behind a plexiglass nose.
• The first XB-42 was delivered to the Army Air Force and flew at Palm Springs, California on 6 May 1944. Performance was excellent, being basically as described in the original proposal; as fast or faster than the de Havilland Mosquito but with defensive armament and twice the bombload. The twin bubble canopies proved a bad idea as communications were adversely affected and a single bubble canopy was substituted after the first flight, a problem that could have been rectified, but the end of World War II changed priorities and the advent of the jet engine gave an alternative way toward achieving high speed.

• AG-42
• The AG-42 rifle (official designation Halvautomatiskt Gevaer 42) was developed by Swedish engineer Erik Eklund while working at company C. J. Ljungman AB. Officially adopted by Swedish army in 1942, this rifle served in Sweden until mid-1960s, when it was replaced in service with 7.62mm AK-4 rifle (license-build HK G3 rifle).

• MKb.42
• In 1939 HWaA (Hitler’s army Weapons command) issued a contract for the development of a “Maschinen karabiner”, or machine carbine (MKb for short), chambered for the new 7.92×33 Kurz cartridge, to the company C.G. Haenel Waffen und Fahrradfabrik.
• The famous designer Hugo Schmeisser led the Haenel development team, which produced the first working prototypes of new weapon by 1942. The new weapon was intended as a replacement for submachine guns, bolt action rifles and, partly, light machine guns for front troops. The MKb.42(H) could be fitted with standardbayonet, and has a wooden butt.

• MG 42
• A cheaper to produce but much more reliable replacement for the MG 34, the MG 42 was officially adopted as the MG 42, and production commenced in 1941.
• In general terms, the MG 42 was a great success. It fulfilled the roles of a light machine gun on a bipod, a medium machine gun (on a newly developed Lafette 42 tripod), and an anti-aircraft machine gun, mounted in single and twin installations, ground and vehicle-mounted. 
• After the WW2 the MG 42, unlike other wartime designs, lived on, as in 1958, the FRG (WestGermany) re-instituted its official armed force, known as the Bundeswehr. 
• The simplicity, low manufacturing cost and high effectiveness of the MG 3 attracted several other countries, which either bought the guns from Rheinmetall (such as Denmark), or obtained manufacturing licenses and build (or at least have built in the past) the same guns domestically (such as Italy, Iran, Turkey, Pakistan and Yugoslavia). In total, at least twenty armies have used or still are using the MG 3 and its versions.
