Peter Coe expressed amazement at a report that a 747 at BA Cardiff had its undercarriage retracted while on the ground. Years ago when I read Nevil Shute's "No Highway", I was skeptical when the hero retracted an airliner's undercart while on the ground to disable the craft. I strongly suspect that the landing gear must be designed to overcenter mechanically such that the actuators don't have enough force to overcome the weight of the plane. The extreme rarity of this type of incident suggests something fail safe about the system. Regards, Roy G. P.S. It was amusing that the paperback I was reading had a cover painting of a jetliner, whereas the text described the propellers bending as the airliner settled to the tarmac.
