I was on youtube and watched a old film about the B-29's air war over Japan.
One of the first reasons taking Iwo Jima was so important was to provide a emergency landing strip
for shot up B-29s on their way back from bombing the home islands of Japan.
It reminded me of a guy I used to know who was there in the early days.
They'd gotten a workable run way built, but they were still getting mortared,
and you could hear gun fire from the Grunts still chasing Jap. soldiers around.
He told of one of the first damaged B-29s to land there on its way back 'home'---
Their other option was ditching along the 'picket' line near one of the ships & submarines on rescue duty, and lose the plane.
A shot up B-29 with several different sizes of holes all in it, chunks of its skin hanging off, came in, and set down.
About that time, mortars started landing,,,,,,,,, much closer than they were comfortable with.
The Aircraft Commander- probably a kid about 25 years old had just gotten out of the plane, followed by the crew.
He looked around, then told his crew to get back on board.
He said, "This place is worse than where we came from". They fired it back up and left.
