Not entirely true, Jim. They were air-burst bombs *in order that*
there would be a minimum of radioactive debris.

They were air bursts because the shock wave spread out, maximizing damage.


Had Little Boy and Fat Man burst at ground level, the situation in
Hiroshima and Nagasaki would not have been nearly so mild.

If it had been a surface detonation, the damage would have been
substantially LESS.
