Germanwings flight crash: Eye witnesses heard 'strange noise' before plane crash

An eye witness said he was used to planes going overhead but the sound made by this particular flight was strange as if it was trying to fly 'really low'

Mystery shrouds the crash of Lufthansa's Germanwings plane that went down in a remote area of the French Alps, killing all 150 people onboard, as the aircraft was touted to have a good safety record, with just 0.14 fatal accidents per million takeoffs.

The crash that took place on Tuesday was unexpected also because the weather conditions were favourable and the flight was traversing the best part of its flight when it crashed, reported Stuff.co.nz.

A local resident, who was outside his home near Digne Les Bains in the southern Alpine hamlet of Beaujeu, said that he heard an unusual sound before the plane crash. He said that he was used to planes going overhead but the sound made by this particular flight was strange as if it was trying to fly "really low." He added that he thought for a moment that it was a military plane. Seconds later, the flight smashed into the ground, killing all onboard.

Another local woman also said that she heard the plane "flying really low," and thought it was a military plane.

The black box of the Germanwings flight 4U9525 has been found and delivered to investigators. They will also look for clues in the debris, victims' bodies, radio communications, maintenance logs and the background and training of the crew.

The plane was flying from Barcelona to Duesseldorf.
