Book ablout a man who meets a stranger who has a crop duster, christian theme maybe?

I think this book has the word feather in the title. The man meets a stranger who gives out crop dusting rides in a bi plane. It seems to me to have a christian or religious theme. Does anyone know the title of this book??Book ablout a man who meets a stranger who has a crop duster, christian theme maybe?
The book is Illusions by Richard Bach. It is not `Christian' although it certainly could be read that way. It's closer to a Buddhist understanding. Great book. There was a feather on the cover of the original printing but the title of the work is `Illusions'.
