Capt. Christopher Stricklin ejected from his USAF Thunderbird aircraft at an airshow at Mountain Home Air Force Base, Idaho, on September 14, 2003. While  making a dive, Strickilin realized he could not pull up in time and ejected after aiming it at a safe place. Stricklin was not injured.

An aviation accident is an occurrence on board an aircraft resulting in injury or death to one or more persons. The U.S. National Transportation Safety Board definition of an aviation accident is as follows:

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 and all such persons have disembarked, and in which any person suffers death or serious injury, or in which the aircraft receives substantial damage.
An aviation incident is an occurrence other than an accident, associated with the operation of an aircraft, which affects or could affect the safety of operations.

Other countries adopt a similar approach, although there are minor variations, such as to the extent of aviation-related operations on the ground, covered, as well as with respect to the thresholds beyond which an injury is considered serious or the damage is considered substantial. A hull-loss accident is one where the damage to the plane is such that it must be written off, or in which the plane is totally destroyed.

History

Since the birth of flight, aircraft have crashed, often with serious consequences. This is due to the unforgiving nature of flight, where a relatively insubstantial medium, air, supports a significant mass. Should this support fail, there is limited opportunity for a good outcome. Because of this, aircraft design is concerned with minimizing the chance of failure, and pilots are trained with safety a primary consideration. Despite this, accidents still occur, though statistically flying is nowadays an extremely safe form of transportation. In fact, the relative rarity of incidents, coupled with the often dramatic outcome, is one reason why they still make headline news. Nevertheless, while the odds of actually getting caught in a plane crash are nowadays distinctly low compared to other means of transportation, the chances of not surviving such a disaster are notably higher.

Many early attempts at flight ended in failure when a design raised to a height for a launch would fail to generate enough lift and crash to the ground. Some of the earliest aviation pioneers lost their lives testing aircraft they built.

The first aircraft fatality in history occurred in 1908 when Lt. Thomas Selfridge was killed in this plane piloted by Orville Wright.  The accident was caused by propeller separation. Orville Wright suffered broken ribs, pelvis and a leg. (17 September, 1908)

Otto Lilienthal died after a failure of one of his gliders. On his 2500th flight (August 10, 1896), a gust of wind broke the wing of his glider, causing him to fall from a height of roughly 56 ft (17 m), fracturing his spine. He died the next day, with his last words being reported as Opfer müssen gebracht werden! ("sacrifices must be made").

Percy Pilcher was another promising aviation pioneer. Pilcher died testing The Hawk (September 20, 1899). Just as with Lilienthal, promising designs and ideas for motorized planes were lost with his death. Some other early attempts experienced rough landings, such as Richard Pearse who is generally accepted to have crash landed (survived) a motorized aircraft in some bushes, unable to gain altitude after launching from it from some height.

The Wright Flyer nearly crashed on the day of its historic flight, sustaining some damage when landing. Thomas Selfridge became the first person killed in a powered aircraft on September 17, 1908 when Orville Wright crashed after propeller failure of his one-passenger plane during military tests at Fort Myer in Virginia.

Causes

About 80 percent of all aviation accidents occur during takeoff or landing (or shortly before and after) and are typically the result of human error and/or unregarded technical problems within an aircraft; mid-air disasters are rare but not entirely uncommon. Among other things, the latter have been caused by bombs as in the 1988 Lockerbie incident, mid-air collisions such as in the 2002 Überlingen crash or in cases of (purportedly) mistaken identity where civilian aircraft were shot down by military (compare Korean Air Flight 007).

An accident survey [link] of 2,147 aircraft accidents from 1950 through 2004 determined the causes to be as follows:

The survey excluded military, private, and charter aircraft.

Safety

Aviation safety has come a long way in over one hundred years of implementation. In modern times, two major aircraft manufacturers still co-exist: Boeing of the United States of America and Airbus of Europe. Both have placed huge emphasis on the use of aviation safety equipment, now a billion-dollar industry in its own right, and made safety a major selling point -- realizing that a poor safety record in the aviation industry is a threat to corporate survival. Some major safety devices now required in commercial aircraft involve:

The NTSB

In the United States, many civil aviation incidents have been investigated by the National Transportation Safety Board. When investigating an aviation disaster, NTSB investigators piece together evidence from the crash and determine the likely cause(s). Some accidents the NTSB has reported include:
