I'd be grateful for any evidence to test my hypothesis that
the Nagasaki bomb-aimer deliberately saved scores of thousands of
lives by dropping that bomb a few miles from the instructed aim
point. The fireball was in fact over a shallow valley slightly
higher than, as well as off to one side from, the city centre.
Possible explanations I'm aware of include:-
* he knew his actual aim point was a few mile off, and would save some lives
* ditto, and had a particular desire to hit a main centre of the
R.C. church for the whole of Japan - the Urakami cathedral
* he got a glimpse thru broken cloud of what he thought was the
racetrack which had been one of his aiming aids, but what he was
actually seeing was a stadium in the 'upland valley' suburbs. This
would entail an honest mistake, not a deliberate mis-aiming.
