I'd say "Project Cancelled" from my school library and then Salamander's "Warplanes of the Future" from my local bookshop were the beginnings of this site :)

First place I saw it back in grade school.  ;)

Jr. High for me. While the '40's and '50's were the Golden Age of "projects," I think the '80s was the Godlen Age of Current Projects Publications. The books published back then  were jam-packed with quality artists impressions of what was on the planning boards. Today there are *far* more bits of art available... but most of it is computer generated crap.

Something I've noticed is that as PowerPoint and similar desktop publishing programs became available, the quality of presentations has gone *down.* In the 1960s, if you had a presentation for the USAF on, say, your neato new fighter design, you had the art department put together a package of drawings and paintings. Today you cobble together some MS Paint sketches yourself. Bah.

*snicker* I've seen at least one humorous piece floating around work that purportedly describes a MSPE (Masters of Science Degree in Powerpoint Engineering) program.  Given all the presentations we required to produc on occassion, it sometimes feels all too true.

"VTOL? Like take-off in a day? "

Found this tiny little concept in Icare from 1971 :
Nuclear powered and 150m span ...   ;D
It takes a long time, before all mistakes are made ...

I've heard some of the military folk referred to as "Powerpoint Warriors"  :D
"DARPA Hard"  It ain't what it use to be.

Version I saw was a seaplane as I recall. 

The great little book "Future Fighters" has a Lockheed painting of this critter. The books author speculates that it was to be a seaplane, but it was strictly land-based.

First place I saw it back in grade school.  ;)

I've got it on my  bedside table now.  ;D Found a copy on Amazon and bought it for myself this past Christmas.

Don't want to go too OT, but  Bill Gunston's above mentioned 'Warplanes of the future' and the similar 'Future Fighters and Combat Aircraft' were outstanding references. That was almost 20 years ago (the X-29 hadn't flown yet!). Is it me or there hasn't been anything comparable since (quality-wise)?
All modern aircraft have four dimensions: span, length, height and politics.   TSR.2 got the first three right - Sir Sydney Camm

Another great BWB resource is this Power Point from Boeing Phantom Works:

Technologies For Subsonic Transport by R.H. Leibeck

www.asme.org/gric/AeroWkshop/presentations/RobertLiebeck.pdf

Includes data on a range of BWB commercial and military proposals including BWB 450G comparision to the A380.

Update: Looks like this link has been deactivated.
