I just love it.
First I have people telling me that there are "to many" aircraft in RSRDC and now I get there not enough in WDAD. The funny thing is that both mods are using the "same files" for aircraft generation.
It should be noted that as far ships and convoys are concerned I have used the "historically accurate" data from a number of sites i.e.
http://www.combinedfleet.com/kaigun.htm
http://home.cogeco.ca/~gchalcraft/sm/
and a number of others.
Convoy generations is based on Senji Yuso Sendan Shi (Wartime Transportation Convoys History), by Shinshichiro Komamiya.
Now if you people have other sources of information then pass it on
