Quote from HN39, post #2842:
Sorry Chris, I didn't say that, and it's not correct.
Apologies for the misinterpretation, HN39, and I stand corrected. I have edited my post #2839 by footnote.
I fully concur that, at FL350, AF447 was not cruising anywhere near "coffin corner". But the tropopause remains of interest, as always, for the reason I stated. Is there a difference of opinion on its altitude in the case of AF447?
