Yeah that to those who said if Joe had been up front on 3407 it wouldn't have happened.... I don't think sleeping on the jumpseat is a big deal (especially not after seeing numerous NWA old-hat 74 CAs do it).... but as far as "needing" someone during a critical phase... if you're asleep on the jumpseat below 10 and we feel we need ya, you'll be woken up.
I have "spoken up" during a red-eye that I commuted from PDX to ATL.... they were given an altitude, read it back correctly, but spun it 100 feet off and confirmed with each other the incorrect alt.... so I said something.... just, "hey, I think they may have said xxx alt not yyy"....
