I was in a Banes and Noble once and found a book strictly about helicopters and to my now regret, I didn't buy it. What I remember about this book is that when you went to the manfacturer, it showed a picture of every variant including that variants prototypes and gave a detailed description of said type. For example, I looked up the Bell 222(my favorite helicopter), and it showed pictures of the prototypes, the A, B, SP, and UT. Flipping through the book, it showed other helicopters in the same regard. It was an amazing book and for the life of me, I can't remember the title!! Does anyone know this book? I remember thinking how it seemed more in depth than Janes in a way since it showed pictures of every variant and protoytype, which is something Janes doesn't do. Thank you for your time.
Yeah, I wish I would have bought it, it was amazing. The thing is, and this is what kills me now, I had the money, but saved it for our trip instead and never found anything that cool from then on and never found the book again.
