Pinnacle Airlines aircraft incident
Could someone please explain why the engines would not relight when much lower down? Was it a "mixture" problem or is there no APU to bleed air?
I also remember somewhere that above a given FL most conventional winged aircraft (ie not Vulcan or Victor stylee) the control surface deflection is limited to half due to mach compressibilty effects? I think it was related to this incident.
Thanks

Oilhead, it was said in reference to the post:
<<Done FL490 in a 4-engined jet ...... but no silly-arse pratting about while there. Idiots.>> I thought it was unnecessary to call them idiots, hence "I expect they'll know better now". I feel the greatest sympathy for them- most pilots on their own without pax will have a lark and do things they're not really meant to. Brit humour isn't really snide anyway.
Shaft, I think the roblem was because of the extreme low speed nature of the flight, the cold soaked engines rotated so slowly, or even stopped, and the cold bearings stiffened and stopped the engines rotating for restart.

Methinks problem was quite the opposite: if I recall correctly, one of the engines was so overtemperatured that its hot section was partially melted. NTSB knows more about it.
Regarding the Darwin awards: they are extremely sarcastic way of honouring the people who improve the mankind´s gene pool by removing their genetic material from it in a spectacular manner. While the manner in which this crew went to join their ancestors was very spectacular, capt (again, if I recall correctly) had two children
and so only earned mention and not the prize
If you haven`t learnt already, please take this accident as reminder that even when you´re flying alone, there are still lot of people who will be affected if something goes wrong.
