Hi All.
There are plans to produce revised and updated versions of the two volumes of American Secret Projects: Jet Fighters and Jet Bombers, but both are probably a couple of years away. My next job is British Secret Projects 4: WW2 Bombers. This was badly delayed by health problems with my elderly mother (now fortunately sorted). I hope to hand the book over before the end of the year, so it should be out in mid-2020.
I then have some other titles to do for Crecy and for other publishers. My first book for Osprey, X-Planes: Jet Prototypes of WW2 is due anytime.
Very best wishes, Tony.
