Main airfields are 1, 2, 3, 4, 5 and 6. These are based on the actual airfields in Japan at the end of the war. other main fields are P59, V123 and P86. P59 and V123 are actually Tokyo, P86 is Nagasaki. The remaining port is placed where Hiroshima would have been, which will appear in the terrain at a later time (but not in time for this scenario).
