Yes its very good - also enjoyed "Firebirds" by Chuck Carlock, a slightly better read in my opinion.
Funny enough I bumped into a guy who - I think - was the pilot/something to do with a Huey which was parked at Helitech 2005. I had just read Chickenhawk and - as he was an american - mentioned I had read it. He got a bit angry as he seemed to have problem with the author, I think he believed that the author had "borrowed" some of the experiences in the book from other people.
Can anyone shed some light on this? Not trying to stir things up, just interested. (I know its been a while but I had forgotton about the conversation until I read this thread!
)
