Upon further digging, I found videos of the rocket-powered aerodynamics testing of 0.133 scale rocket powered Convair XFY-1 "Pogo" models. I previously have posted a couple of still shots of the Pogo-equipped rocket but the videos show a lot more detail. I am still surprised to see a propeller-driven airplane design tested atop a rocket. Until I saw NASA Cultural Resources' videos, I didn't realize the airplane models were released for free-flight. However, I guess it makes sense that the would be.
Pogo model prep and flight test on May 17, 1954.
Hover tests conducted at NASA Langley Research Center's Free Spinning Tunnel. If I do another PMC of the Pogo, I'm going to use this paint scheme.
