"attaching it's MLG to the trunions, allowing the gear to be pushed up through the dry bays instead of overloading the wing structure. This is a Boeing design feature not utilized on the MD-11."
(BA038)
This feature created the only serious injury to a passenger, as I recall. The gear rolled up and fractured the gentleman's leg, badly.....on the right side of the aircraft......
As to Narita, a case can be made that McD over engineered the mains and the NG. Had the mains collapsed the aircraft would likely not have rolled, due the broken port side main spar.... On the second nose plant, the gear held, and the nose rebounded to about a sixty degree angle? This contributed to the aircraft's completed inversion.....and all hope lost of a crew survival...
There is strong, and there is "too strong"?
