There was some sort of an event taking place at the CAF SoCal wing the following day and so Minsi III was towed out of the hangar for an engine run-up and test. I wasn't allowed onto the ramp whilst the engine was running and so the pictures are quite back-lit. However, here she is being towed back into the main hangar after the tests were fininshed. This airframe fell into disrepair after WWII and was discovered as a derelict hulk in Minnesota with the data plate missing. As a result the true identity of the plane may never be known.
