[QUOTE=Troo believer;9741080] Imagine if the refuelling hose fractured. What then. A major fuel spilll under the aircraft with passengers on board. Who is responsible? Certainly not the engineers since they maybe else where attending to other aircraft. Traffic staff? No training for this scenario. Airport manager. No training and not licenced to operate the systems. So tell me at ETD-30 who is responsible? QUOTE]
NOT the pilot that is behind a locked door that has no idea of the fuel below the aircraft.
It is beyond belief that you think you have responsibility at this point - you must be a pilot.
The person at this point in charge is the person that the refuller calls depending on the airport/country that the aircraft is located - should they tell (demand) the persons stay on the aircraft (via captain) I expect you will obey their "command" you are not in charge (in most countries) like that or not.
