Sorry Graeme, I have nothing to post.
I must take a sabbatical from winning challenges and take the time to learn how to make some
. Open House I guess.
Yes, the 101 C flew, see Wiki
The VJ 101C X-1 flew 40 aerodynamic flights, 24 hover flights and 14 full transitions. During these tests the sound barrier was broken, for the first time by a vertical take-off aircraft, but on 14 September 1964 a defect in the autopilot caused a crash. On July 29, 1964 the VJ 101 C flew at Mach 1.04 without use of an afterburner.
Edit to say that it did not merely "fly" but flew. I had quickly read that it had crashed, and did not realize that it had this impressive flying record.....
