India Four Two: Excellent book. Recommended.
Concur, a great read for anyone interested in the subject. Much of the focus is on the Red Eagles flying the MiGs at Tonopah (next door to Area 51/Groom lake proper) in the 1970's to the 1990's. Exposed scores of pilots to the MiG 17, 21 and 23. I found the parts on the MiG-23 especially interesting with pilots swearing it was trying to kill them every time....
Touches a bit on the earlier MiG programs at Groom lake. I hope Mr. Davies or someone else can do a companion piece on the evaluation side at Groom- the Red Hats. Would love more technical detail on how the maintainers kept them going, how the pilots got used to them, etc.
