And it does not request rocket science on return but chokes, steps, fuel, baggage to be tossed on board and at least a half-decent loadsheet with the same reg on it and the side of the aircraft. No business pax, no first pax, no dangerous goods, no cargo, no mail, no containers, no pallets, no catering, no load planning, no high-loader, no live animals, nothing fancy but the very basics.
All very easy when you have the staff and equipment. If you don't, then it's not so easy - not rocket science is it !
