Quote:In November 1944, the US Army Air Force launched a 111-plane B-29 strike against Tokyo, the first raid since the morale-boosting Doolittle Raid of 1942. From then until August 13, 1945, the United States would attack Tokyo 25 times, 20 from B-29s based in the Marianas and five from US Navy carrier task forces. The campaign included the single deadliest air raid in human history, when around 100,000 people were killed by the firestorm created by the Operation Meetinghouse raid of March 10, 1945.
