Hi all,
As an ancient, I readily admit to no longer having all the figures at hand to do a "back-of-the-envelope" calculation.
My gut reaction is that it will take less fuel to just taxi to the take-off point, and then back from the turn-off after landing, than it will take to carry the (few hundred pounds?) WheelTug across the Atlantic.
Not to mention the WheelTug will still need fuel for the APU.
Does anybody have an envelope handy?
