"One of the unusual features of the fighter commented on by test pilots was the fact that, at high altitude and high speed, the BMW 801 engine produced a pair of contrails which started immediately behind the exhaust exits and completely hid the wings."

 

 

Hadn't heard of that before, but that's not saying much. If it's confirmed by sources, then it would be a nice piece of eye candy!
