Hiryu:
I wish I could but not being a ship maina I don't know of better sources for Hiryu and other IJN carriers than the already published ones. It is amazing that they burned almost of ALL the photos of the ships (and planes) right after the war's end. I can only say that the Document A-11 is the first ever document in which I saw and read some of the details of the carriers of ours.
Micdrow-sama,
>Ahhh yes
Yes. I am recently annoyed with shortage of time to read documents and books and even to look at this site. And I got early this month two volumes out of five of British Aviation written by Harald Penrose. They are good books!
