Thanks, Cwatters , JonDC9 et al.
It did come over a bit that the atmosphere on the flight deck was a little "hilarious" before the problem occurred (and even a little after it started)
And I take the point about hypoxia (I did wonder if they were perhaps a little late getting on the O2)
Yes, I did notice that - once the severity of the problem was evident, the guys on the ground did seem to take a while to give frequencies, vectors etc.
Hope I did not sound too "accusing", and thanks to all for the clarification on the "med tests". That's just the way it came over, and I had tried (Google, All-the-web) to find more info but could only find the same report, or newspaper reports.
The guys were probably "clowning a bit to "whack it to the edge (literally) of the envelope", but sorry they didn't get it down and only suffer a "smacked wrist" from the Boss
