MUSTANGS over TOKYO

I saw your youtube on the Mustangs over Tokyo, who flew out of Iwo Jima. And I commented on an interview of a soldier who guarded the Seabees while they were rebuilding that vital airport there. He had a rough time of it, as there were a lot of Japs still there in that extensive network of deep caves built on that island. There was a lot of controversy about capturing that island, but the Mustangs did not have the fuel capacity to get back to the Marianas (where the B29 bombers flew out of)There were a lot of crashes at that airport, from Mustangs that gave out of fuel just before getting there and because of the initial bad shape of the airport with all the bomb craters etc.
