There was NO paperwork
Ah indeed. So was the case involving a fatal Chinook crash in the Falklands in the mid eighties, killing yet more of my friends!
Deep servicing of an HC1 had involved removal, and replacement of the aft pylon (a fairly major piece of engineering endeavour??)
NO supporting paperwork was raised. Who even knows if any suitable protocol was followed? Nontheless, the first time it moved into forward flight, all aboard perished. Including some of Valkyrie's colleagues; engineers accompanying the first test flight.
Just to remind those unfamiliar: The a/c was seen flying in glorious weather at approximately 500', when it very slowly entered a vertical dive from which it never recovered. Impacting the ground at extremely high speed (and with one of it's occupants attempting to leave beforehand!) the only radio call transmitted was the middle portion of the phrase; "******* hell"
It's not just pilots that cause accidents my friend!
BTW
The aircraft in question was not cleared to transit at that altitude
Please enlighten us with your familiarity with this case.
Or accept you are utterly ignorant of the
FACTS and are simply bumping your gums!
