Not so sure the MLG sheared, that's the problem. Attached to the Main Spar, all load transfers to the wing, which broke off. The NLG surely didn't fail, if only it had. Any bounce is -G, not the wings strongest resistance format.
Had the MLG remained intact on the 777 at LHR, what might have resulted? Ruptured Hull? Instead, the a/c belly skid to a standstill, no deaths. The MD11 needn't be stressed to land on the Carrier, eg another McD, F-4.
Had the NLG failed, the a/c may not have bounced to pitch up and reload the wings, causing the roll onto its back.
Given the choice, I would prefer my wing remain attached rather than the gear.
