I will share what brought me to that particular jet (the VJ 101).
I was doing a google search for Century fighters, and saw a reference to a XF-109. This led me to the Bell D-188A, which has swivel engine mounts for VTOL operations on the wingtips.
Unfortunately, Bell didn't make a full scale working/flightworthy jet version of this design, so the only pics I could find were primarily models and static displays.
However, this led me to the discussion about similar craft, and the VJ 101 came to my attention.
Two VJ 101's were built. One crashed during testing, and the other one was eventually put into a museum.
Notable achievements of this model (from the Wiki) were achieving Mach 1.04 without afterburners, multiple aerodynamic flights, hover tests, and transistions. All of this was achieved in the early 1960's, and of course provided valuable flight testing data for future VTOL jets on the drawing boards in various countries.
