"It only takes one person to 'ditch' a 777 - perhaps someone who had been doing regular practice at landings at sea level in the Indian Ocean on his home 777 sim?
If that one person wanted to 'go down with the ship' there would be no life rafts etc.
ELTs have a close on 100% failure record which the industry seems to have willingly accepted."
Why would someone train themselves to kill all their pax, carry out a survivable ditching and then "go down with the ship"? That hypothesis makes no sense at all.
