“The plane just got approval to increase their elevation to 15,000 feet when contact was lost.”

WHAT???? The plane would not have been at 15,000 in that location, much less below that.
He would have been at maybe 30,000 at that point.

no, if he was just half way across Long Island, there was no way he was above 20K

They dont climb that fast with passengers with a 7 hour flight ahead of them, they dont need to

Plus, I’ve been to those beach areas, specifically the Morichies, 15K is about right, they still look big in the sky

I thought that AF447 was at somewhere between FL300 to FL350 ,,, that 50,000 number is the reported top of the weather (although hail can overshoot the clouds tops on the updraft)...

More importantly ,, I heard reports that the ocean depth where AF447 was thought to have gone down was somewhere just over 20,000’ ... do we have a better idea of the location and depth now for blackbox retrieval?

I was relying on the wikipedia article here: TWA Flight 800
