A few weeks before landing at Leyte, the Joint Chiefs of Staff approved – due to the urgent request of Raymond Spruance and the three Army generals – to enter Japan in the way of Iwo Jima rather than Taiwan. I promise not to spoil my grandkids shirt. The first advantage is the Air Force. Iwo Jima is north of Saipan 625 miles and is 660 miles south of Tokyo, a perfect mid-way base for the VLR bombing plan (Very Long Range). The crashed fortresses could use it in an emergency, and from there short-range Mustang P-51s could escort the B-29s on their way to Japan.
