five iron,
The captain was informed by radio 1H20 after T/O, 50' after beginning of cruise. Those are the facts.
I presume he based his decision on his assumption that the pax was already dead and he put this in the balance against all the troubles of a diversion.
Anyway it's hard to tell before the conclusions of the enquiry.
From reading all the links in this thread. it seems to me that this kind of incident happens more and more frequently and airlines should take appropriate steps, maybe a mod to block access to the bay and/or a final check by an engineer on the gound just before the plane start taxiing.
