“That theory won’t get airborne. I’ll grant that you could get it on the ground, just don’t buy the surface holding up for a takeoff with useful load.”
There was a retired 777 pilot on Fox about thirty minutes ago who addressed exactly what we are discussing. When asked where could hijackers hide this plane? He stated that there are plenty of old air strips around the world built during previous that could be used. He also addressed your contention concerning taking off. He did say that while landing the plane on a shorter runway than desired would not be an issue, taking off with a full load could be a problem. So, it seems to me, assuming the aircraft has been snatched for a nefarious purpose, the question is for what purpose was the plane high jacked? Keep in mind that there would probably be only a few people on board and cargo could be removed. And, depending on the location of the plane in relation to the location of the objective, a full load of fuel may not be required. And, of course, the length of the runway is a critical variable. So, there you have it. Go figure...
I still think it is a sub.
