B. Destruction caused by the fires, either started directly by the
great heat radiation, or indirectly through the collapse of buildings,
wiring, etc.
4. The actual tonnage of T.N.T. which would have caused the same blast
damage was approximately of the order of 20,000 tons.
5. In respect to their height of burst, the bombs performed exactly
according to design.
6. The bombs were placed in such positions that they could not have
done more damage from any alternative bursting point in either city.
7. The heights of burst were correctly chosen having regard to the
type of destruction it was desired to cause.
8. The information collected would enable a reasonably accurate
prediction to be made of the blast damage likely to be caused in any
city where an atomic explosion could be effected.
