Lack of alert a sign of catastrophic failure — expert

One of the early theories being explored by aviation and security experts is that the disappearance of an EgyptAir flight from Paris to Cairo may have been caused by an explosive device.

Air travel expert Julian Bray said no alert being made could mean the airliner suffered a “catastrophic failure” possibly as a result of an explosion.

“It has to be a catastrophic failure because everything went dead and they wouldn’t have had time to get a message out. It’s gone into the deepest part of the Mediterranean.”
