 A grand total of 282 of the 339 B-29s launched for "Meetinghouse" made it to the target, 27 of which were lost due to being shot down by Japanese air defenses, mechanical failure, or being caught in updrafts caused by the fires.Damage to Tokyo's heavy industry was slight until firebombing destroyed much of the light industry that was used as an integral source for small machine parts and time-intensive processes.Firebombing also killed or made homeless many workers who had taken part in the war industry.
