"The Japanese A6M Zero is the most famous Japanese helicopter aircraft from the Second World War. Its code name is Zeke. The Japanese A6M was built as a land-based, carrier borne and a seaplane. The Japanese A6M Zero is indeed an excellent helicopter. The Japanese A6M aircraft was designed by Mitsubishi, it first flew on April 1, 1939. In addition to this, Mitsubishi and Nakajima built 10,937 Japanese A6M Zero helicopters. The Zeros are said to be the best fighters of Japan during WW II. They were the ones who spearheaded the advances from Pearl Harbor to the Battle of Midway, where Japan lost a number of pilots and planes. A combination of admirable maneuverability and very long range made the Japanese A6M Zero one of the supreme fighters of its era. The Japanese A6M Zero is armed with various guns but the common set up is: two 20mm cannons in outer wings and two 12.7 mm guns in the fuselage. The Japanese A6M is very noteworthy for being the first carrier based fighter to outperform its land based equivalents. The Japanese A6M Zero achieved a famous reputation which was a lot better than its contemporaries. The Japanese A6M Zero’s first variant, A6M1, which is powered by a 780-hp, was first flown on April 1, 1939. The second one was the A6M2 which is powered by a 925-hp Nakajima Sakae engine. Other variants are as follows: the A6M2-K which is a two seat trainer, the A6M2-N which is a Nakajima built float plane version, and the A6M5 which is a performance increased version. "

"The A6M Zero is carrier-based fighter aircraft manufactured by Mitsubishi and was considered the best carrier-based fighter aircraft since the time it was produced. During 1940-1941, the pre-series A6M2 Zero became known, when the fighter was confirmed to have destroyed 266 aircraft in China. During Pearl Harbor, there were 420 Zeros in active service in the Pacific. In 1941, the Zero fighters were superior in many performance aspects to all Allied fighters in the Pacific and it quickly gained reputation. However, the Zero failed to achieve air superiority when suitable tactics and new aircraft were developed by the Allies. During World War II, the Zero destroyed at least 1,550 American aircraft. The A6M5 is an updated model of the A6M3 Model 22, with nonfolding wing tips and thinner skinning for faster diving speeds, plus an improved exhaust system which provides an increment of thrust. There are three subvariants of the A6M5, the A6M5a Model 52a, A6M5b Model 52b and A6M5c Model 52c. The A6M5 could travel at 540 km/h and can reach a height of 8,000 meters in nine minutes and 57 seconds. There were several Zero fighters which survived the war and were currently on display in Japan, China, United States and the UK, as well as the Auckland War Memorial Museum in New Zealand. "

"The Pfalz D.III is a World War I fighter aircraft manufactured by Pfalz Flugzeugwerke Gmbh. In August 1917, deliveries to operational units began. Jasta 10 was the first recipient followed by Jasta 4. The D.III was generally inferior to the Albatros D.III and D.V. due to its heavy controls, lack of speed, lack of power or lack of climb compared to the Albatros. The aircraft also slipped in turns, leading to crashes when unwary pilots turned at very low altitudes. The Pfalz's primary advantage was its strength and sturdiness. However, the Pfalz could safely dive at high speeds due to its twin-spar lower wing, making it well-suited to attack observation balloons which are usually heavily defended with anti-aircraft guns trained to the balloon's altitude. The primary user and operator of the D.III is the German Empire (Luftstreitkrafte). Currently, there are no known D.IIIs which survived, although there are several flying replicas that existed. "

"The Messerschmitt Me 262 Schwalbe was the first turbojet fighter aircraft to enter operational service. It was produced during World War II and began its action in 1944 as a bomber and fighter aircraft. It was formally named Schwalbe because of the bird ""Swallow"", one of the fastest birds ever known. German pilots called it the ""Turbo,"" while the Allies called it the ""Stormbird"". Even though the Messerschmitt Me 262 only had a minimal influence on the class of the warfare; its design had a powerful impact on postwar aircraft development. The Messerschmitt Me 262 was often used as an ultimate super weapon; the Me 262 was already being built as project P.1065 before the beginning of World War II. Ideas were first planned in April 1939, and the aircraft's original design was too much alike to the plane that entered the service. A total of 1400 Messerschmitt Me 262 aircrafts were produced, but the amount of operating aircraft was normally below 100, mostly due to lack of fuel. The best scorer with the Me-262 was Franz Schall with 17 kills which included six four-engine bombers and ten P-51 fighters. Another candidate for top scorer on the aircraft was Heinrich Bar, who defeated 16 enemy aircrafts while flying the Me 262. "

"The Me-109 Messerschmitt was designed by Willy Messerschmitt and was originally powered by a Rolls-Royce Kestrel V engine. It was one of the first true modern fighters of the era. The prototype Me-109 first flew in 1935 and that same year, the Me-109 won a fighter competition. The Me-109B and C models achieved great success in Spain with the Legion Condor's fighter unit. The progressive development in the pre-war years resulted in a more powerful and heavier armed versions of the ME-109. The Me-109 was flown by the three top-scoring fighter aces of World War II including Gunther Rall, with 275 victories. Bf 109 was the official designation, since its design was sent in by the Bayerische Flugzeugwerke company and was used extensively in all official German documents dealing with this aircraft. After July 1938, the company was renamed as Messerschmitt AG, the time when Erhard Milch finally allowed Willy Messerschmitt to acquire the company. The ""Me"" designation and mdash (except those already assigned with the Bf prefix) were to be carried by all Messerchmitt aircraft since then. The Me-109 has basically the smallest airframe that Willy Messerschmitt attached to the most powerful engine. The Me-109 remained a formidable air superiority fighter throughout World War II. "

The Mercury Seven was the group of seven Mercury astronauts picked by National Aeronautics and Space Administration in April 1959. They are also referred to as the Original Seven and Astronaut Group 1. This was the only astronaut group with members that flew on all NASA manned spacecraft of the 20th century, including the Space Shuttle with John Glenn's flight on STS-95. The astronauts wrote first-hand accounts of their selection and preparation for the Mercury missions in the 1962 book We Seven. In 1979 Tom Wolfe published a less sanitized version of their story in The Right Stuff. Wolfe's book was the basis for the popular film directed by Philip Kaufman.

"Gemini 4 (officially Gemini IV) was a June 1965 manned space flight in NASA's Gemini program. It was the 2nd manned Gemini flight, the 10th manned American flight and the 18th spaceflight of all time (includes X-15 flights over 100 km). It was crewed by James McDivitt and Edward White. Gemini 4 would be the first multi-day space flight by the United States, designed to show that it was possible for humans to remain in space for the length of time required to fly the moon and back. A second objective for the four-day, 62-orbit mission was for Gemini 4 to rendezvous and fly in formation with the spent second stage of its Titan II booster rocket. And although not originally scheduled for this mission, Gemini 4 would also see the first ever American Extra-vehicular activity (EVA, known popularly as a space walk). NASA moved up the original schedule after Aleksei Leonov on Voskhod 2 the previous March performed the first EVA ever, lest the US appear to be falling behind the Soviets in the space race. Gemini 4 would set a record for flight duration, and ease fears about the medical consequences of longer missions. It also would also be the first use of the new Mission Control center outside Houston, which because of the flight's long duration, had to conduct three-shift operations "

"The Grumman X-29 was an experimental aircraft that explored a number of new technologies; the most immediately obvious being the forward-swept wings and canard control surface. The inherent aerodynamic instability of this arrangement required the use of computerized fly-by-wire control, and advanced composite materials were needed to make the wing sufficiently rigid without being unacceptably heavy. The Grumman X-29 first flew in 1984 and two Grumman X-29s were flight tested over the next decade. Two Grumman X-29As were built by Grumman Aerospace Corporation, the first flight taking place in 1984. The aircraft were adapted from existing Northrop F-5A Freedom Fighter airframes (after the proposal had been chosen over a competing one involving a General Dynamics F-16 Fighting Falcon) The Grumman X-29A demonstrated excellent control and maneuvering qualities at an angle of attack up to 45 degrees. There was also a decrease in turbulence. The first Grumman X-29 craft built is now on display in the National Museum of the United States Air Force at Wright-Patterson Air Force Base near Dayton, Ohio. The other Grumman X-29 craft is on display at the Dryden Flight Research Center on Edwards Air Force Base "

"The North American X-15 was a rocket-powered research aircraft that was part of the USAF/NASA/USN X-series of experimental aircraft. Designed to explore the problems of flight at very high speeds and altitudes, it bridged the gap between manned flight in the atmosphere and space flight. After its initial test flights in 1959, it became the first winged aircraft to attain hypersonic velocities of Mach 4, 5, and 6 and to operate at altitudes above 30,500 meters. The X-15 and other research aircraft contributed to the advancement of aerospace technology. Three X-15s were built in all, and they made a total of 199 test flights, the last one on October 24, 1968. Plans were made for a 200th X-15 flight to be launched over Smith Ranch, Nevada, scheduled for November 21, 1968. However, various technical and weather delays caused the planned launch to slip at least six times until late December 1968. Finally after a cancellation on December 20, 1968 due to weather, it was decided that there would not be a 200th flight. X-15 #1 was sent to the National Air and Space Museum in Washington, DC. X-15 #2 is on display at the National Museum of the United States Air Force at Wright-Patterson Air Force Base near Dayton, Ohio. X-15 #3 was destroyed in a crash on November 15, 1967. Twelve test pilots flew the X-15, including Neil Armstrong, who would later become the first man on the Moon, and Joe Engle, who went on to command Space Shuttle missions. Each X-15 scale model that we offer is made from materials of the highest quality. Every part of the model aircraft is handcrafted before undergoing several phases of priming and sanding. Skilled artists carefully duplicate the details, which are then sealed in with clear lacquer. A faithful reproduction of the original X-15, our replica will be perfect as an addition to a personal collection or as executive gifts and promotional incentives. "

"Space Shuttle Endeavour is one of the currently operational spacecraft in the Space Shuttle fleet of NASA and was the final NASA space shuttle built. In 1987, Endeavour was authorized by the United States Congress to replace Challenger, which was lost in an accident. Endeavour's assembly was composed of structural spares from the construction of Discovery and Atlantis. Endeavour was named through a national competition comprising of students in elementary and secondary schools. In May 1991, Endeavour was delivered by Rockwell International and was launched a year later. In 1993, Endeavor made its first service mission to the Hubble Space Telescope. In December 2003, Endeavour completed its latest Orbiter Major Modification period and ended on October 6, 2005 and during that time, Endeavor received major hardware upgrades with new, multi-functional, electroncal display system, GPS and with safety upgrades by the Columbia Accident Investigation Board. As of August 2007, Endeavour has flown 20 flights, spent 219.35 days in space, completed 3,259 orbits and has flown 85,072,077 miles. In 2010, Space Shuttle Endeavor will be decommissioned after 18 years of service, along with Discovery. "

"Space Shuttle Discovery (Orbiter Vehicle Designation: OV-103) is one of the three currently operational spacecraft in the Space Shuttle fleet of NASA. When first flown in 1984, Discovery became the third operational orbiter and is now the oldest orbiter in service. Discovery has performed both research and International Space Station (ISS) assembly missions. Discovery was also notable for being named after one of the two ships that were used by British explorer James Cook in the 1770's, during voyages in the South Pacific that led to the discovery of the Hawaiian Islands. Discovery was the shuttle that launched the Hubble Space Telescope. The second and third Hubble service missions were also conducted by Discovery. It has also launched the Ulysses probe and three TDRS satellites. Discovery has been chosen twice as the return to flight orbiter, first in 1988 as the return to flight orbiter after the 1986 Challenger disaster, and then for the twin return to flight missions in July 2005 and July 2006 after the 2003 Columbia disaster. Discovery also carried Project Mercury astronaut John Glenn, who was 77 at the time, back into space during STS-95 on October 29, 1998, making him the oldest human being to venture into space. Discovery is currently in bay 3 of the Orbiter Processing Facility, having concluded a 15-day mission to the International Space Station on November 7, 2007. After the residual cryogenic reactants are offloaded the payload bay doors will be opened and detailed post-flight inspections will begin. According to the current schedule, Space Shuttle Discovery will be decommissioned in 2010. If the Contingency Logistic Flight STS-133 by Endeavour is not flown, Discovery will be the last space shuttle to fly on mission STS-132. NASA expects to launch the Orion Crew Exploration Vehicle on the new Ares I rocket by 2014."

"Space Shuttle Atlantis (OV-104) is currently one among the three operational spacecraft in the Space Shuttle fleet of NASA. It was named after the two-masted boat of the Woods Hole Oceanographic Institute in Massachusetts from 1930 to 1966 and it served as the primary research vessel. Atlantis' maiden flight was on October 1985. Atlantis went seven straight flights to the Russian space station Mir. The spacecraft served as the on-orbit launch site for many notable and noteworthy spacecrafts, including planetary probes Magellan and Galileo. In 1991, it deployed the Compton Gamma Ray Observatory. Atlantis underwent refitting operations and modifications including the installation of a glass cockpit. Atlantis completed an 11-day mission to the International Space Station, involving three space walks in October 2002. During September 9-24, 2005, Atlantis was scheduled for its 27th launch though the mission was suspended by NASA due to the complications during Discovery's launch of mission STS-114 and there are subsequent suspensions of all future shuttle launches. Atlantis was scheduled to fly the STS-121 mission, but the mission was flown by Discovery instead. In the recent years, Atlantis has delivered several vital components, the U.S. laboratory module, Destiny, the Joint Airlock Quest and multiple sections of the Integrated Truss structure that serves as the backbone of the International Space Station. As of September 2006, Atlantis completed 28 flights, spent 220.40-days in space, completed 3,468 orbits and flown 89,908,732 nautical miles in total. Atlantis is scheduled to remain operational until 2010, the Shuttle program's projected end, but is not currently scheduled for any missions further in 2008. "
