In the book Project Cancelled there is a whole chapter devoted to the British Army project for a "Jumping Jeep" which could leap across obstacles using jump jets/rotorfans. The winning bid from BAC was under development until the mid 60s when it was cancelled on cost and practicality grounds...

Some time ago in a website that in the meantime disappeared from the Internet I found several pictures of an armoured personnel carrier that had been designed (and built as a prototype) in Canada sometime in the 1950s. According to the website its designation was the XA-20. Unfortunately there...

In a German forum (http://www.network54.com/Forum/240281/message/1090833080/) I have just found a very intersting drawing showing what is allegedly a tank designed in Germany by Daimler-Benz/Porsche in the mid-1950s for India. Here is the drawing: Has anybody here ever heard of such a...

Pometablava... Joe Baugher's website has a whole paragraph on the subject. From the website http://home.att.net/~jbaugher1/f4_1.html The design of what was eventually to emerge as the McDonnell F-4 Phantom began in August of 1953. The McDonnell design team was headed by Herman Barkley...

As you all know, in the unbuilt projects research business, squeezing stone sometimes gives intriguing info... Looking last night to the Martin projects list at the end of Narkiewicz/Thompson (publisher) book, I suddenly realized that the XB-68 bomber bore the 302A project number, BUT the...

In the book "Valkyrie - North American's Mach 3 Superbomber" they indicate that North American continued developement of the F-108 even after it was cancelled. They have a "1960" configuration that is a little puzzling. Either the canopy and windows shrunk considerably or the aircraft as a...
