The autopilot on the Germanwings Airbus A320 that crashed in the French Alps on Tuesday was switched to descend to 100 feet, its lowest possible setting, before it began its fatal plunge, according to data from a specialist aviation tracking service, Reuters reported.
Online web tracking service FlightRadar24 said its analysis of satellite tracking data had found that someone had changed the altitude to the minimum setting possible of 100 feet: well below the crash site lying at about 6,000 feet.
"Between 09:30:52 and 09:30:55 you can see that the autopilot was manually changed from 38,000 feet to 100 feet and 9 seconds later the aircraft started to descend, probably with the 'open descent' autopilot setting," Fredrik Lindahl, chief executive of the Swedish tracking service said by email.
He said FlightRadar24 had shared its data with French crash investigators at their request.
