Was going to say I think that's the Graf Zeppelin but I didn't register that the Hindenberg was also represented.
I'm not going to be able to write a Major Scott book in the short term but on the basis of what has been said on this thread I think I will do it after my Mexico vs. Texas Naval War of 1842 book (that's a pleasantly obscure story).
If anyone has any leads to personal papers or anecdotes relating to Major Scott and his fellows could they PM me so I can start collecting information.
