A few changes to what I posted above about which runways were actually operational at Iwo and how long they were-
and where they were located.
Change 1: I was under the impression from everything I had read that the B-29 runway at what the Americans named Central Field (Japanese No2) was merely an extension of the original main 5225 foot Japanese runway. But the pre and post US occupation diagrams and maps were not jibing with each other.
The Japanese main runway had a heading of 57/237 and was nearly parallel to the Airfield No1 main runway (later to become the US South Field). Problem is that all of the diagrams and photos of the US airfields show a marked changed in the heading of the main runway at Central Field- 10 degrees: from 57/237 to 67/247.
The screenies I posted earlier show the sirfields as I had them laid out going on the assumption that the new runway at Central fields was just an extension of the old Japanese runway at No2 Airfield on the same heading. I came to the conclusion that this just couldn't be true.
Change 2: Which US runways were actually operational? Earlier I was operating under certain assumptions, based on information from certain sources, that only the 6000 foot runway at South field and an 8500 foot runway (eventually paved to 9800 feet) at Central Field were ever operational. Turns out that new information and images convinced me that actually 3 runways were operational and paved. And that the 8500 main runway at Central field was actually very quickly paved to 9800 feet. And that the runway at North Field (unfinished Japanese Airfield No3) was an operational fighter strip paved to 5000 feet.
So, I went back and basically started over again and this time I am pretty sure that while not perfect we have a fairly accurate representation of what was happening with the American airfields at Iwo.
Screenies below show the current situation- drawn in only with FSSC so far with a very basic scenery object layout. Notice how much better the Central/North Field layout fills in the space when the main runway is lengthened to 9800 feet. Mush more like the photos.

Haven't decided yet whether to do a texpoly ground texture or just a simple VTP1 with G2Kv4.
Still need to add roads also.
