747Focal : from an earlier post :
quote :
American Airlines B-727 reg.#N844AA , and it was converted to a fuel tanker last year. It has ten 500 gallon aluminum tanks bolted to the floor with 4 inch valves on each tank joined together by 4 inch high pressure hoses leading to the aft where refueling is accomplished. There is also a very unique vent system which allows almost zero fumes into the aircraft. The tanks are held to the seat tracks in four corners buy half inch bolts.(I would hate to see where the tanks would end up if a few G's were pulled)
I do not think 5000 gal + full 727-100 does makes up for a full 767-300 , but I stand to be corrected.
