In religion

40 is probably the most frequently used number in the Bible and corresponds to many major events. For example,

• During the great flood it rained for forty days and forty nights [Genesis 7:4, 12, 17,8:6].
• Isaac was forty years of age when he married Rebekah [Genesis 25:20].
• Moses’ life is divided into three 40-year segments, separated by his fleeing from Egypt, and his return to lead his people out.

• STS-40
• Although designated STS-40, this was in fact the 41st flight of the Space Shuttle and the 11th flight of Columbia. Its mission was to conduct the Spacelab Life Sciences (SLS-1) experiments, the first spacelab dedicated to life sciences research. This included experiments that explored how the heart, blood vessels, lungs, kidneys and hormone-secreting glands respond to microgravity, the causes of space sickness and changes in muscles, bones and cells during the microgravity environment of space flight and in the readjustment to gravity upon returning to Earth.
• Launch took place on June 5, 1991, 9:24:51 a.m. EDT. It was originally set for May 22,1991, but postponed less than 48 hours before launch when it became known that a leaking liquid hydrogen transducer in orbiter main propulsion system which was removed and replaced during a leak testing in 1990, had failed an analysis by vendor. Engineers feared that one or more of the nine liquid hydrogen and liquid oxygen transducer protruding into fuel and oxidizer lines could break off and be ingested by the engine turbopumps, causing engine failure.
• In addition, one of orbiter five general purpose computers failed completely, along with one of the multiplexer demultiplexers that control orbiter hydraulics ordinance and orbiter maneuvering system / reaction control system functions in aft compartment.
• New general purpose computer and multiplexer demultiplexer were installed and tested. One liquid hydrogen and two liquid oxygen transducers were replaced upstream in propellant flow system near 17-inch disconnect area, which is protected by internal screen. Three liquid oxygen transducers replaced at engine manifold area, while three liquid hydrogen transducers here were removed and openings plugged. Launch reset for 8 a.m. EDT, June 1, but postponed again after several attempts to calibrate inertial measurement unit 2 failed. Unit was replaced and retested, and launch was rescheduled for June 5. Launch Weight: 251,970 lbs.
• The Commander STS-40 was Marine Corps Col. Bryan D. O’Connor. Other crew, Air Force Lt. Col. Sidney M. Gutierrez (Pilot), James P. Bagian, M.D.; Tamara E. Jernigan, Ph.D.; and Margaret Rhea Seddon, M.D. The payload specialists, Francis Andrew Gaffney, M.D., and Millie Hughes-Fulford, Ph.D.

In politics

• South Dakota ranks 16th in size among the 50 states. It was the 40th state to join the Union in 1889. South Dakota encompasses 77,123 square miles, averaging 10 people per square mile.

• Ronald Reagan, former actor and Governor of California (1967-75) was the fortieth President of the United States of America, from January 20, 1981 to January 20, 1989. His Vice President was George H. W. Bush.

Ronald Reagan 40th President of the United States of America

• Reagan’s Presidency was notable for at least two incidents.
• On March 30, 1981, only 69 days into the new administration, Reagan, his press secretary James Brady, Washington police officer Thomas Delahanty, and Secret Service agent Timothy McCarthy were struck by gunfire from would-be assassin John Hinckley, Jr. outside the Washington Hilton Hotel. Although “close to death” during surgery, Reagan recovered and was released from the hospital on April 11, becoming the first serving U.S. President to survive being shot in an assassination attempt. The attempt had great influence on Reagan’s popularity; polls indicated his approval rating to be around 73%. Reagan believed that God had spared his life so that he might go on to fulfill a greater purpose.
• A couple of videos, the first rather long but interesting in that it shows the live story of the assassination attempt developing, and the second President Reagan recounting the assassination attempt from his personal perspective.

.

.

• Another controversial incident involving President Reagan happened in summer of 1981 when PATCO, the union of federal air traffic controllers, went on strike, violating a federal law prohibiting government unions from striking. Reagan declared the situation an emergency as described in the 1947 Taft–Hartley Act, and stated that if the air traffic controllers “do not report for work within 48 hours, they have forfeited their jobs and will be terminated”. They did not return and on August 5, Reagan fired 11,345 striking air traffic controllers who had ignored his order, and used supervisors and military controllers to handle the nation’s commercial air traffic until new controllers could be hired and trained. As a leading reference work on public administration concluded, “The firing of PATCO employees not only demonstrated a clear resolve by the president to take control of the bureaucracy, but it also sent a clear message to the private sector that unions no longer needed to be feared.”

In sport

• In football (soccer), forty is generally considered to be the number of points that a Premier League team (or, by extension, a team in any 20-team league with a standard home-and-away season) needs to avoid relegation.
• In baseball, each team in Major League Baseball is allowed to have 40 players under major-league contracts at any given time (not including players on the 60-day disabled list). From September 1 to the end of the regular season, teams are allowed to expand their game-day rosters to include the entire 40-man roster.
• In tennis, the number 40 represents the third point gained in a game. A score of 40-40 (three points each) is called “deuce”, at which time a player must score two consecutive points to win the game.

• Beginning with the 2013 season, forty cars will run each race in NASCAR’s second-level Nationwide Series.
• The jersey number 40 has been retired by several North American sports teams in honor of past playing greats or other key figures:
• In Major League Baseball: the Houston Astros, for Don Wilson; the Pittsburgh Pirates, for Danny Murtaugh, most noted as the team’s longtime manager.

• In the NBA: the Denver Nuggets, for Byron Beck; the Detroit Pistons, for Bill Laimbeer.

• Curtiss P-40 Warhawk
• Manufactured by Curtiss-Wright Corporation of Buffalo, New York and designed by Donovan Berlin, the Curtiss P-40 Warhawk’s first flight was on 14 October 1938. Over 13,700 were built and during its twenty year life it was used by the United States Army Air Forces, the Royal Air Force, Royal Australian Air Force, Royal Canadian Air Force, Royal New Zealand Air Force, and many others. A single-engine, single-seat, all-metal fighter and ground attack aircraft, it was used extensively by most Allied powers during World War II, and remained in front line service until the end of the war.
• The British Commonwealth and Soviet air forces used the name Tomahawk for models equivalent to the P-40B and P-40C, and the name Kittyhawk for models equivalent to the P-40D and all later variants.

• PPD40
• The PPD (Pistolet-Pulemyot Degtyarova) was developed by famous Russian small arms designer Fedor Degtyarov. It was formally adopted by the Red Army in 1935 and entered limited production as the PPD-34. Made in small numbers, it was mostly relegated for NKVD use, mostly for border guards. Slightly modified in 1938, it was then produced until 1939 in PPD-34/38 variation, with newly developed 71 rounds drum with long neck.
• After the Winter War experience (1940 war between USSR and Finland), new version of PPD has been rapidly developed, with the most visible change being the two-part stock, cut to accept new pattern of drums, which had no neck. This became the PPD-40.
• After the outbreak of the Great Patriotic Warin 1941, it was soon been discovered that the PPD-40 is less than ideal for wartime production, so it was quickly replaced by the more efficient and inexpensive PPSh-41, which appeared in great numbers and was widely used by Red Army.

• MP40
• One of the most famous submachine gun designs in history, the M.P. 38 submachine gun started its life under requirements from German Heereswaffenamt (HWA, Army Weapons Office), which saw the need for a compact submachine gun, suitable for use by armored vehicles crews and paratroopers.
• German arms-making company Erfurter Maschinenfabrik Gmbh, better known under its trade name Erma, began the development of a new weapon under HWA specifications. It was manufactured for just 2 years, when it was replaced in production by externally similar, but less expensive MP-40, which used more stamped parts instead of machined parts, found in MP-38.
• There also were minor variations in design of MP-38, such as shape of cocking handle etc. MP-40 was also produced in a number of variations, which differed in shape of certain parts; also, toward the end of the war, several production shortcuts were introduced to save the costs of manufacturing. probably the most interesting variation of the MP-40 were the MP-40-II and MP-40-II. These guns featured dual magazine housings which hold two magazines in a laterally sliding bracket. This increase the total ammunition capacity “in the gun” to 64 rounds, in a desperate attempt to catch up with 71-round magazine capacity of Soviet PPSh-41. The later variant, MP-40-II, was made in limited numbers, but turned out to be a failure – sliding dual-magazine housing was a constant source of jams and failures, and was very sensitive to dirt and fouling.
• Nevertheless, the MP-40 submachine guns were of good design, and set the pattern for so called “second generation” of submachine guns (“first generation” being represented by the wood-stocked and carefully machined MP-18, MP-28 and the like). The second generation weapons usually were of compact design, and made using mostly steel stampings and pressings, or castings.
• Many MP-40 that survived the WW2, continued to serve up until late 1970s or early 1980s, in few European armies such as Austrian or Norwegian.

.

• Taurus MP40
• During the 1990s Taurus replaced in production its MT-12A submachine gun (licensed copy of the Beretta PM-12) with another foreign design, this time purchased from Chile.
• Originally known as the FAMAE SAF, in Brazil it is made in a slightly modified form as the Taurus MT-9 (in 9mm Luger) and MT-40 (in .40SW, especially for the Brazilian police forces that favor this caliber). In this case, the MT index stands for Metralhadora Taurus – Taurus Submachine gun, and the digits denote a caliber.
• Taurus also makes an interesting offshoot of the MT-40, the CT-40 semi-automatic carbine, which is also intended for police and security use but is restricted to semi-automatic fire and has somewhat longer barrel.

.

• SVT-40
• The SVT-38 (Samozaryadnaya Vintovka Tokareva – Tokarev Self-loading rifle) was originally adopted in the 1938 after more than 20 years of the research and development, done by famous Russian arms designer Fedor Tokarev. 
• This rifle was made in relatively large numbers (more than 1 million made prior to 1945), and was originally issued as a standard infantry rifle, replacing the obsolete Mosin-Nagant M1891/30 bolt action rifles. A few SVT-40 were also manufactured in the sniper variant, (only about 50 000) equipped with scope mounts and telescopic sights, but accuracy was not sufficient. 
• The SVT-40 had a somewhat controversial reputation. It was highly regarded by the enemies (Finns and Germans) and it was a very sought-after war trophy, re-issued to both German and Finnish troops. On the other hand, it was often considered unreliable and over-complicated by the Soviet troops (when comparing with old Mosin-Nagant rifles), but it was more to the poor training and maintenance, than to the rifle itself. Some better trained and educated Soviet troops, such as Sea Infantry (Marines, which always were some kind of elite in the Soviet army) used the SVT-40 with great deal of success.

.

• Husqvarna M/40
• The ‘Luger-like’ L-35 pistol was developed by the Finnish designer Aimo Lahti and manufactured by Finnish company VKT from 1935 until 1985 or so. It was adopted as a standard sidearm for Finnish army in 1935. 
• In 1940, Sweden purchased a license for Lahti pistol, simplified it and began production as a Husqvarna M/40 pistol. Due to simplification and poor quality of steel used in M/40, these guns tended to crack when fired 9mm “submachinegun” ammunition, and also M/40 were less reliable than original L-35s, so in the 1980s almost all M/40s were recalled from military service and replaced by older m/07 pistol (licensed Browning M1903 pistols) as an emergency feature.

.

• HK-UMP40
• The UMP (Universal Machinen-Pistole = Universal Submachine Gun) had been developed by the Heckler & Koch company of Germany in the mid- to late- 1990s and first appeared on the markets in 1999. The key idea behind the UMP was to create a lightweight and powerful submachine gun, that was also cheaper than one of the H&K’s flagships, the MP-5. UMP, being targeted primary for USA law enforcement market, first appeared in .45ACP and .40SW chamberings, and later – in 9mm. 
• The UMP is a blowback-operated select-fire submachine gun, being fired from the closed bolt. The receiver is made from the polymer, the controls are fully ambidextrous. UMP can be fired in full-auto, in single shots, and in 2 or 3 round bursts (optional). UMP also has bolt hold-open device, which traps the bolt in the open position when the last round from magazine had been fired. UMP has side-folding buttstock and two set of picatinny rails – one on the top of the receiver, and the other – on the forend. These rails can accept wide variety of sighting and other equipment, such as red-dot sights, laser pointers, tactical grips and flashlights. The barrel has quick mount for snap-on silencer.

And finally,

Last, but definitely not least, perhaps one of the greatest ever inventions also carries the ’40’ tag. It is WD-40.

WD-40 is the trademark name of a penetrating oil and water-displacing spray, developed in 1953 by Norm Larsen, founder of the Rocket Chemical Company, in San Diego, California.

The term ‘WD-40’, is an abbreviation of the phrase “Water Displacement, 40th formula”.

Larsen was attempting to create a formula to prevent corrosion in nuclear missiles, by displacing the standing water that causes it. He claims he arrived at a successful formula, which is primarily composed of various hydrocarbons, on his 40th attempt.

WD-40 was first used by Convair to protect the outer skin, and more importantly, the paper thin “balloon tanks” of the Atlas missile from rust and corrosion.

WD-40 first became commercially available on store shelves in San Diego in 1958

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);

• 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.)

• 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.

• 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.
