I figured that might be one factor, though you could always have an
OCR version for easy access with links to images of the Real McCoy
as you currently have.  Then again, when you have is considerably
better than nothing, so I'm not really complaining.

Hang on just a minute there!  Your entire argument is that a failure
of the cargo door was the cause of each of these crashes.  If a bomb
blew out the door, the departure of the cargo door is simply part of
the breakup and not part of the cause.  Engines probably departed the
airframe, too, but that in no way leads to the conclusion that PA 103
was attributable to the same cause as the El Al 747-200F in Amsterdam.

>Right, could have been bomb in 182 that blew door but door definitely went.

Same thing, you've just thrown out your entire point, unless you claim
that a failure of the cargo door triggered the bomb!

By what mechanism might increased air speed trigger an alleged failure
of the cargo door?
