Nice to see them making the effort though. After all it is important. Hopfully if they keep up the brainstorming, they may just catch on to something that will work. Every little helps.
However, I can see how the landing gear of a B 747 or an A340 could be strained by being towed a longer distance than normal at MTOW. Does anybody know the MTOW of a 747or an A340? As for the idea of towing the aircraft before takeoff. How about towing them back to the terminal after landing when they are far lighter? How much stress would this cause the landing gear? Probably pritty close as, they are not designed for this kind of operation. Also you have to think about the delays this may cause other airlines while waiting for the start ups. May end up costing the same in fuel due to the knock on effects.
They will come up with something better, they always do! Can't see ground at major airports to happy with the idea of change though.
Anyways,
good night all,
