Air crash


An aviation accident is defined by the Convention on International Civil Aviation Annex 13 as an occurrence associated with the operation of an aircraft, which takes place between the time any person boards the aircraft with the intention of flight until all such persons have disembarked, where a person is fatally or seriously injured, the aircraft sustains damage or structural failure or the aircraft is missing or is completely inaccessible. If the aircraft is destroyed or severely damaged so that it must be written off, it is further defined as a hull loss accident. Annex 13 further defines an aviation incident as an occurrence, other than an accident, associated with the operation of an aircraft which affects or could affect the safety of operation.

The first fatal aviation accident was the crash of a Rozière balloon near Wimereux, France, on June 15, 1785, killing its inventor Jean-François Pilâtre de Rozier as well as the other occupant, Pierre Romain. The first involving a powered aircraft was the crash of a Wright Model A aircraft at Fort Myer, Virginia, USA, on September 17, 1908, injuring its co-inventor and pilot, Orville Wright, and killing the passenger, Signal Corps Lieutenant Thomas Selfridge.

583: The Tenerife airport disaster, which occurred on March 27, 1977, remains the accident with the highest number of airliner passenger fatalities. 583 people died when a KLM Boeing 747 attempted to take off without clearance, and collided with a taxiing Pan Am 747 at Los Rodeos Airport on the Canary Island of Tenerife, Spain. There were no survivors from the KLM aircraft; 61 of the 396 passengers and crew on the Pan Am aircraft survived. Pilot error was the primary cause, as the KLM captain began his takeoff run without obtaining air traffic control clearance. A contributing factor was the dense fog. The KLM flight crew could not see the Pan Am aircraft on the runway until immediately before the collision. The accident had a lasting influence on the industry, particularly in the area of communication. An increased emphasis was placed on using standardized phraseology in air traffic control (ATC) communication by both controllers and pilots alike. Furthermore, all members of the cabin crew are now able to question the captain's judgment concerning the safety of the airliner.
