Well done, meleagertoo, it’s the M2F1. I suspect Noyade knew the answer, but he was pipped at the post!
A "homebuilt" proof of concept glider for all of NASA’s lifting bodies.

I have trouble imagining flying a glider where you have to look at the towplane or runway through a window in the nose!
Looking at the probe on the nose, I wonder if they would have been better off with a glider yaw-string, rather than the almost obscured yaw-vane.

meleagertoo has control
PS I don't think that is Chuck Yeager in the picture. Possibly Milt Thompson?
