In late 1942 the germans captured a crashed spitfire and took it to berlin for comparative testing against the BF-109. To more accurately gauge the performance difference the spitfire was mated to the Daimler-benz ebgine that was being used in the BF-109. The result was found to be more manuevrable and faster than eith plane. The result was...
The Schmittfire!
The good news for everyone on the west side of the channel was that the plane was destroyed before it could be produced. Aeroplane Heaven's Schmittfire.
