Very interesting! I think this really belongs in the Postwar projects section and as a modest contribution to the subject, here are three photos of the X-Jet prototype (don't know if there were more than one) and the planned WASP cabin vehicle design for the Marines.
A flying lecturn...just the thing for tech-bros to escape press conferences:

Mr. Musk, what is your position on-
WHISSSSSSS
"I can't hear you..."
 
Reveiw of the Garrett STAMP. Unfortunately, I can't find the name of the doucment I pulled these pages from.

On an interesting note, from 1978:
https://apps.dtic.mil/sti/pdfs/ADA057663.pdf
A generalized ring vortex system was utilized to determine the pressure distributions and streamline shapes within a three-dimensional jet-diffuser ejector.

Experiments verified the utility of the method and resulted in a measured performance exceeding that of the original STAMP (Small Tactical Aerial Mobility Platform) Ejector, while avoiding the use of the large, protruding end plates required by that ejector.

Ground effect tests on the new design showed improved performance compared to similar tests on the STAMP Ejector over the entire range of ground clearances.

This was a project of the Flight Dynamics Research Corporation, carried out on behalf of the Naval Air Development Center.
