Rob, I think some airmen weren't identified. My Uncle was and he's not on the headstone. He is buried in our hometown in Missouri. I didn't know about the Memorial in St. Louis until a few years ago. Do you know whether your cousin was?
Shawn. There is a Facebook group CCK Air Base Taichung Taiwan you will half to join. I got these copies from an Airman who was there at the time. You can search posts with the crash date. Lots of them remember. My Uncle Rex Bundy was on the plane.
