Mike,
Where the He!! are you nowadays? I haven't seen you at one of the Society for Aviation History (
http://www.sfahistory.org) lunches in quite a while and I hear you've left the California sunshine for the other side of the Atlantic.
You do have a point that the book is U.S.-centric, however, Mike, since you're a friend I think it's time for a geography lesson -- Swamp Ghost and P-61 (recovered from New Guinea), Japanese aircraft recovered from Indonesia, Glacier Girl (Greenland), Marauders (Canada), Corsairs (Latin and South America), and Mustangs (Latin and South America) -- thus about half of the book deals with aircraft recovered from outside the United States!
Maybe not the recoveries you've cited, but the book is, in my opinion, well-balanced geographically.
Note that if the book sells well, then there may be a follow-on that covers more of the worldwide recoveries (but note that many important U.S. recoveries didn't make it into this book -- only for space considerations). That said there's still the problem of content. Getting quality images of some of these recoveries is, frankly, next to impossible. From the acknowledgements you'll see that more than 100 people gave generously of their time and photo collections to make "Hidden Warbirds" what it is. That alone says a lot about the book and the people who work to recover and preserve historic aircraft.
As I mentioned in an earlier post, this book can't be all things to everyone for the simple fact that there's not enough real estate in 250 pages to cover every wreck ever recovered.
Why don't you PM me with your contact info and we can chat more off-line? I'd like to know what you have in your collection that could be used in the next book.
Since I'm collecting material for a follow-on book, I'd be happy to hear from WIXers who have good quality photos/scans they'd be willing to lend to a potential follow-on book.
Best,
Nick
