First Hillis is not listed in Olynyk's Starts&Bars.

Second these stories should always be taken with a grain of salt, at best under scrutiny. Its amazing how many similar stories / reports have mainly originated from the American side. You'd believe that half the Luftwaffe was flying B-17, B-24s and captured US fighters. Seeing some captured a/c during the occupation clearly fed this wartime believe.

At least take it from the operational side.

Using a captured a/c in combat is more of a liability than an asset, since the risk of friendly fire is greatly enhanced. So all your forces need to know the difference between your friendly enemy type and the general enemy - this would mean that a LOT of germans would have known about these air operations, yet where is this german side of the story?

The investment of maintaining a valuable enemy type in the air for testing purposes outweighs any use of it flying single combat sorties, unsupported btw, that could not be flown much more effectively by readily available types. So why fly a single P-47 when you could operate a Staffel of Fw 190s?

KG 200's operational history is relatively well documented, and their clandestine operations revolve mainly around long range, behind the lines, air drops and communications flights. Not air combat...

So there are three likely answers.

1. The whole event is made up
2. The enemy fighter was misidentified
3. The P-47 was actually a friendly - a case of friendly fire
