A lot of professional pilots no longer read this forum due to the drivel frequently expressed by emotive people who may be very competent in the field they work in but do not understand a lot of the basics of running an airline.
or may be, if they do their homework properly and don't spend too much time on FlightSim, they will when they leave school.
OLDBALBOY - think you may have been fortunate with your experience of DoB, I have brought several pax from the Middle East into LHR, hoping to get to a London specialist but left it too late, police and an MD every time, delay usually less than ten minutes. Body bags on board? Obviously an airlines choice, two of the majors I flew for did.
My experience only but bodies placed in a toilet, in a sitting position, on the floor, can be removed and taken off in a wheel chair, (the type designed for use within the aircraft), when all other pax are off.
