Trouble is none of us are in a position to change anything at root cause level. (that is I've not read a post from anyone who possesses such powers).
Good point.
How many Airline Pilots are there world wide ?
If there are 500,000 and 10% all posted an IFALPA designed letter from their local post office to ICAO headquarters on the 1st of June that called for ICAO compliant countries to limit 2 crew graveyard shifts to 11 hours for single sectors and 9 hours for double sectors, at least someone would have to stand in front of the to cameras and say that they will think about it.
Fanciful I know but it would literally save lives if implemented and the Airlines would still make their dough.
