Well, I've never seen a U2, but I have seen the Blackbird in air shows.
At mach 3, cruising speed for the Blackbird, heating due to friction is
a serious problem. It is not at the speeds the U2 flies, which is
similar to that at which commercial airliners fly. If it's a problem
for the U2, it should be a problem for 747s, Airbus 300s etc. You don't
see many of them leaking fuel all over the ground.
