Last night I was listening to this man on Ham Radio (KG6RLP) and he was telling us that a while back this B747 had flown into an ash cloud from an erupting volcano and had its all 4 engines fail. The aircraft was flying at about 39000 feet (FL390) and plumeted until about 11000 or 9000 feet until they had finally restarted all engines. He also stated that the B747 suffered airframe damage from the extreme G-forces.
Had anyone heard about this story? By the way, he is an experienced private pilot and to ALL people that think private prop aircraft are unsafe, than you are all wrong. He told us that it is just CARELESSNESS!!. That some pilots wont even do a walk around. He also told this story about this one pilot that he went up airborne forgetting that he still had his aircraft's flaps locked up from a piece of nail. (He had the nail there to protect the flaps from moving around from the wind) But evidentally he forgot to take it out and just crashed after a few hundred feet from the ground and crashed on a tree. All people were killed in that crash.
