People underestimated the ability of firefighters and others on the ground to extinguish fires caused by bombing.

“precise and only a very small fraction of it actually hit and then people also underestimated the extent to which people on the ground could like firefighters and so on could just sort of go around the city and put out fires from bombs that were falling on structures they overestimated the amount of economic damage that it would do they underestimated how economically costly it would be like basically you're sending these aircraft and then they're getting shot down well an aircraft is very expensive”
