Britannia used to fly them SOU-TFS (about 4 hrs) non stop with (I believe) a full load of passengers and their bags. SOU's runway is 1723m long and has a few near obstructions. To give you idea of how impressive that is the E195/737/A320 can just about make it to AGP/FAO offf of SOU's runway, a mere 2 1/2 hours flight. That must have been some takeoff!
