Operation Meetinghouse, the B-29 firebombing raid on Tokyo of March 9th/10th, 1945, is thought to be the most destructive air raid in history. What a mess, but it looks like not many to help clean up.
Hey, that looks like one of those wood gas units in the trunk of that car, conserving fuel for the military.
Fortunately only five months later we had improved the bombing technique so it only took two planes instead of 334, saving tons of fuel and probably a lot of overtime pay. Also the bodies were vaporized saving all that cleanup they had in Tokyo.
