The Wright brothers, Orville Wright (August 19, 1871 - January 30, 1948) and Wilbur Wright (April 16, 1867 - May 30, 1912), are generally credited with making the first controlled, powered, heavier-than-air flight on December 17, 1903. In the two years afterward, they developed their flying machine into the world's first practical airplane, along with many other aviation milestones.

In 1878 Wilbur and Orville were given a toy "helicopter" by their father. The device was made of paper, bamboo and cork with a rubber band to twirl its twin blades, and about a foot long. The boys played with it until it broke, then built their own. In later years, they pointed to their experience with the toy as the initial spark of their interest in flying.

The Airbus A380 is a double-deck, four-engined airliner manufactured by Airbus S.A.S. It first flew on 27 April 2005 from Toulouse–Blagnac Airport. Commercial flights began in late 2007 after months of testing, with the delivery of the first aircraft to launch customer Singapore Airlines. During much of its development phase, the aircraft was known as the Airbus A3XX, and the nickname Superjumbo has also become associated with the A380.

The A380 is double decked, with the upper deck extending along the entire length of the fuselage. This allows for a spacious cabin, with the A380 in standard three-class configuration to seat 555 people, up to maximum of 853 in full economy class configuration. Only one model of the A380 was available: The A380-800, the passenger model. It is the largest passenger airliner in the world superseding the Boeing 747. The other launch model, the A380-800F freighter, was canceled and did not join the ranks of the largest freight aircraft such as the Antonov An-225, An-124, and the C-5 Galaxy.

• 2013 – Solar Impulse aircraft HB-SIA completes the second and longest leg of its trip across the continental United States, arriving at Dallas-Fort Worth International Airport in Texas after a 957-mile (1,541-km) flight from Phoenix Sky Harbor International Airport in Phoenix, Arizona, at an average speed-over-ground of 52 mph (83.7 km/h), reaching an altitude of 27,000 feet (8,230 meters). The flight, which takes 18 hours 21 minutes, sets a new world distance record for a solar-powered flight, exceeding the previous record, also established by HB-SIA, in a flight from Switzerland to Spain on 25 May 2012.^[1][2]

CET, headed for Langley AFB, Virginia. At least two North American F-100 Super Sabres from RAF Lakenheath, a C-130 from Mildenhall, and two RAF English Electric Lightnings are sent aloft to try to make contact with the stolen aircraft. The Hercules crashes into the English Channel off Alderney (5000N, 0205W) ~90 minutes later. In the last transmission from Meyer, to his wife, in a link-up over the side-band radio, he stated "Leave me alone for about five minutes, I've got trouble." There is speculation whether the Hercules was shot down. Some wreckage was recovered but the pilot's body was never found. Meyer had been arrested for being drunk and disorderly earlier in the morning in the village of Freckenham and had been remanded to quarters, but sneaked out to steal the Hercules.

Colquhoun makes a high-speed run over South Marston airfield, experiences a sudden nose-down pitch as the starboard wingtip folds upwards. Using only the rudder - the ailerons had jammed - he makes a wide circuit and touches down at ~200 knots (370 km/h), coming to a stop just short of the end of the runway with a burst tyre. He receives the George Medal for saving the aircraft under daunting circumstances.

• 1948 – In the early evening, ex-RAF Handley Page Halifax C.MK 8, registered G-AIZO, ex-PP293, and operated by Bond Air Services Ltd. carrying a cargo of apricots from Valencia, Spain, crashes at Studham, Bedfordshire while on a Standard Beam Approach (SBA) to RAF Bovingdon in bad weather. After a steep turn to port and losing height rapidly, the Halifax sideslips towards the ground until, seeming to recover and flying straight and level and with engines at full power, the aircraft strikes the ground flat and disintegrates, breaking into its component sections. Miraculously, the crew escape alive. After initial suspicions that the cargo may have shifted in flight, the subsequent AAIB report blames loss of control by the pilot while the aircraft was too close to the ground for recovery.
