Tony, a remote control system would still have to use the flight control system present on the jets. So the remote controller would run into the same problems you believe would stop a human pilot.
The person in that video presented no evidence to back up his claims that no pilots could hit the buildings. The claim that they had to reduce to landing speed to do so is ludicrous. I say again, it is not that difficult. Bill Lear is a case in point with some of his claims about this sort of thing. He can sound very convincing right up to the point he starts giving in depth knowledge about secret bases on the moon. I suspect that caller of the same mental state.
You see videos of passenger aircraft doing low fast passes at air shows. They either fly along a 45 metre wide runway or beside it. That is the skill required and, say in the case of the RNZAF 757, there is nothing in the training of those pilots out of the ordinary.
We do unusual attitude recovery training in flight simulators. I have flown the 767 simulator at speeds far in excess of 400 knots during a recovery. It is not a problem.
I personally don't feel the need to prove to you what I do for a living but my name is Mike Glynn, those that have been here for some time know that.
