And the U-2 was rumored to have twisting trailing edge landing gear,
so landing in a crosswind in a crab was fine.

I have a friend that flew B-52's, C-5A's, and I believe 747's, all with
steerable landing gear. He said that it is a great idea in theory but that
with conventional gear you at least know that if the fuselage is lined up
with the runway then so is the gear. With steerable landing gear you have
to guess at the correction angle setting and then guess again at whether the
gear is aligned with the ground track at touchdown. He said that he
preferred to land with the gear straight whenever it was at all possible.
