Others, which are reached by walking up a single flight of stairs, have balconies.

In the general engagement which followed, Abner was defeated and put to flight.

American Airlines Flight 77 was a passenger flight which was hijacked by five al-Qaeda terrorists on September 11, 2001, as part of the September 11 attacks.

This results in an in-flight oscillation of the arrow in which its center flexes out to one side and then the other repeatedly, gradually reducing as the arrow's flight proceeds ; this can be clearly seen in high-speed photography of an arrow at discharge.

Consequently, rotation creates an equalling of such turbulence, which, overall, maintains the intended direction of flight i. e. accuracy.

There are several major vendors of flight avionics, including Honeywell ( which now owns Bendix / King ), Rockwell Collins, Thales Group, Garmin and Avidyne Corporation.

Following the Glorious Revolution, the line of succession to the English throne was governed by the Bill of Rights 1689, which declared that the flight of James II from England to France during the revolution amounted to an abdication of the throne and that James ' son-in-law, ( and nephew ) William of Orange, and his wife, James ' daughter, Mary, were James ' successors, who ruled jointly as William III and Mary II.

Pilots and flight attendants were trained to adopt the " Common Strategy " tactic, which was approved by the FAA.

A pioneer of aeronautical engineering, he is credited as the first person to separate the forces of lift and drag which are in effect on any flight vehicle,

American 11 was hijacked 15 minutes after the flight departed by Omari and four other hijackers, which allowed trained pilot Mohamed Atta to crash the Boeing 767 into the North Tower of the World Trade Center as part of an attack that killed thousands of people.

Abd-ar-Rahman IV was murdered the same year he was proclaimed at Cadiz, in flight from a battle in which he had been deserted by his supporters.

Thus for an ion which traverses a 1 m flight path, across a time of 2000 ns, given an initial accelerating voltage of 5000 V and noting that one amu is 1 × 10 < sup >− 27 </ sup > kg, the mass-to-charge ratio ( more correctly the mass-to-ionisation value ratio ) becomes Z amu / charge.

Its surfaces therefore are symmetrical and not uneven like the aerofoils which give the returning boomerang its characteristic curved flight.

In 1996 Charlie Ellington at Cambridge University showed that vortices created by many insects ’ wings and non-linear effects were a vital source of lift ; vortices and non-linear phenomena are notoriously difficult areas of hydrodynamics, which has made for slow progress in theoretical understanding of insect flight.

Baddeck would be the site of his experiments with hydrofoil technologies as well as the Aerial Experiment Association, financed by his wife, which saw the first powered flight in the British Empire when the AEA Silver Dart took off from the ice-covered waters of Bras d ' Or Lake.

In the period between the World Wars the United Kingdom developed the Larynx ( Long Range Gun with Lynx Engine ) which underwent a few flight tests in the 1920s.

Egypt is identified in the Bible as the place of refuge that the Holy Family sought in its flight from Judea: " When he arose, he took the young Child and His mother by night and departed for Egypt, and was there until the death of Herod the Great, that it might be fulfilled which was spoken by the Lord through the prophet, saying, Out of Egypt I called My Son " ( Matthew 2: 12 – 23 ).

A festival, the Septerla, was held every year, at which the whole story was represented: the slaying of the serpent, and the flight, atonement, and return of the god.

These had started in 1944 with the famed Whirlwind which was originally developed to make a flight simulator for the US Navy, although this was never completed.

On August 26, 1959, Ike was aboard the maiden flight of Air Force One, which replaced the previous Presidential aircraft, the Columbine.

Doors which lead from interior, pressurized, sections of an aircraft to exterior or unpressurized areas can pose extreme risk if they are inadvertently opened during flight.

Copilot William Rataczak informed Cooper that the aircraft's range was limited to approximately under the specified flight configuration, which meant they would have to refuel once again before entering Mexico.

A precise search area was difficult to define, as even small differences in estimates of the aircraft's speed, or the environmental conditions along the flight path ( which varied significantly by location and altitude ), changed Cooper's projected landing point considerably.

There are many physiological changes in the body associated with fear, which can be summarized as the " fight or flight " response.

Any movement ( from straight and level flight for example ) results in signals to the computer, which automatically moves control actuators to stabilize the aircraft.

* 1937 – The Pedaliante achieves the first sustained 1 km human-powered flight.

* March 18 – The Bossi-Bonomi Pedaliante achieves the first sustained 1-km ( 0. 621-mile ) human-powered flight, with a catapult launch.

It takes about 30 days before a chick achieves flight capability.

* February 6 – The Short Mayo Composite aircraft achieves its first separation in flight.

* May 31 – A Short Type 184 from the Royal Navy seaplane carrier Engadine achieves the only British aerial reconnaissance flight of the Battle of Jutland, reporting the sighting of three cruisers and ten destroyers of the German High Seas Fleet before a broken fuel pipe forces it to end the mission.

* March 25 – During a test flight with afterburner, the Lockheed XF-104 achieves a speed of Mach 1. 79 ( 1, 181. 4 mph, 1, 901. 3 km. hr ).

* 6 April – Horatio Phillips achieves the first, limited, powered heavier-than-air flight in the United Kingdom when his multiplane makes a hop.

* 8 August – Wilbur Wright achieves a flight of 389 feet ( 118. 5 m ) at Kitty Hawk, North Carolina, in the Wright 1901 glider.

Because of the increase in drag approaching Mach 1, aerodynamicists and aviators disagreed on whether supersonic flight was achievable.

Image showing shock waves from NASA's X-43A hypersonic research vehicle in flight at Mach 7, generated using a computational fluid dynamics algorithm. On September 30, 1935 an exclusive conference was held in Rome with the topic of high velocity flight and the possibility of breaking the sound barrier.

In the decade preceding faster-than-sound human flight, aeronautical engineers referred to the speed of sound as Mach's number, never " Mach 1.

* 1964 – The North American XB-70 Valkyrie, the world's first Mach 3 bomber, makes its maiden flight from Palmdale, California.

The German EWR VJ 101 used swiveling engines mounted on the wingtips with fuselage mounted lift engines, and the VJ 101C X1 reached supersonic flight ( Mach 1. 08 ) on 29 July 1964.

However, propfan engines, which are very similar to turboprop engines, can cruise at flight speeds approaching Mach 0. 75.

The Dassault Mirage IIIV achieved transition from vertical to horizontal flight in March 1966, reaching Mach 1. 3 in level flight a short time later.

Building a Mach 3. 0 + aircraft out of titanium posed enormous difficulties and the first flight did not occur until 1962.

Created in 1945, Matra ( Mechanics / Aviation / Traction ) was the company behind several technological projects: creating a twin-engine airplane prototype able to travel at 800 km / h, breaking the sound barrier at Mach 1. 4 in vertical flight for the first time in Europe.

Shadowgraph of the detached shock on a bullet in supersonic flight, published by Ernst Mach in 1887.

The comments about restoration of flight control and cessation of buffeting above Mach 1 are very significant in a 1946 document.

XS-1 flight number 50 is the first one where the X-1 recorded supersonic flight, at Mach 1. 06 ( 361 m / s, 1, 299 km / h, 807. 2 mph ) peak speed ; however, Yeager and many other personnel believe Flight # 49 ( also with Yeager piloting ), which reached a top recorded speed of Mach 0. 997 ( 339 m / s, 1, 221 km / h ), may have, in fact, exceeded Mach 1.

By the 1950s many combat aircraft could routinely break the sound barrier in level flight, although they often suffered from control problems when doing so, such as Mach tuck.

In 1961, the sky was no longer the limit for manned flight, as Yuri Gagarin orbited once around the planet within 108 minutes, and then used the descent module of Vostok I to safely reenter the atmosphere and reduce speed from Mach 25 using friction and converting velocity into heat.

During the flight, the aircraft achieved Mach 1 on dry power only ( supercruise ).

They are said to permit Mach 11 flight at altitudes and mach 7 flight at sea level.

Theoretically, a PDE can operate from subsonic up to a hypersonic flight speed of roughly Mach 5.
