The book "Dark Eagles" by the late Curtis Peebles mentioned at the bottom of page 247 and the top of page 248 the following passage about the alleged "F-121" Sentinel being a Northrop-built equilateral triangular aircraft designed to take off and land vertically with an antigravity engine based on a drawing reportedly given to Peebles by an anonymous source. In case you haven't noticed, Andreas Parsch recently updated the page "Cover Designations for Classified USAF Aircraft" to omit all mention of "F-121" because he correctly recognized that all rumors about the "F-121" being a hypersonic spyplane were bogus. Any claim mentioned by Peebles about Northrop building an antigravity engine-powered aircraft with the "F-121" label seems very dubious at best because antigravity propulsion remains the stuff of science fiction. By the way, when was the Hughes Electronics poster (shown in attached link) issued?
