sorry can't resist.soles on board will be twice the number of souls on board.unless of course the pax are carrying spare shoes as well then, its anybody's guess
I'm feeling guilty now.In the U.K. we asks for souls on board or person's on board(P.O.B.) when an aircraft has an emergency.We would expect this number to include the PAX and crew as it is passed on to the emergency services on the ground for their benefit rather than ATC's.
