sample quote

If an aircraft is equipped with an ejection seat, the location of the crash site is normally proximate to where the ejected pilot lands. But there have been cases where an aircraft continued flying for hundreds of miles after the pilot ejected.

In 1989, for example, a Soviet Air Force Mikoyan MiG-23 crashed in Belgium, but that was 600 mi. from where the pilot ejected over Poland. The pilot ejected after the afterburner failed and the aircraft began descending, but after his ejection the engine kept running and the aircraft continued flying on autopilot.
