There is a lot yet to learn about the Turkish Airlines Boeing 737-800 crash at Schiphol.
Just about everything, in fact.
But this was an accident - like many recently - that was survivable by all, or at least most, of the people on board.
An unconfirmed report in the Turkish English language daily newspaper Hurriyet has just alleged that at least one of the pilots survived the crash, even if he might not have survived rescue.
The imminent week's issue of Flight International reveals that the rescue crews could not get through the anti-hijack security door to the flightdeck, and eventually they had to recover the three pilots' bodies through a hole they cut in the roof.
Is this the scenario rescue crews face in a future accident in which pilots are injured such that they can't either evacuate themselves or operate the flightdeck door?
If so, the designers have some fast work to do to improve this sad legacy of the 9/11 terrorist suicide attacks, because the safety of pilots following an otherwise survivable accident is not a negotiable issue.
And this is not the only disadvantage the cockpit security door has brought to today's airline operations, as any pilots or cabin crew will tell you.
