I posted this in the aviation section but it warrants repeating here in STORIES.
I should tell you (as best I can remember) something that a Sherman tank commander told me many years ago (sorry no real sources here other than his name - Joe Shlickman - he was head of NYC Transit when I knew him).
Joe said that they had entered Germany from Belgium early '45. I do not know where in Germany. He and his tanks were in a wide open area. Overhead they saw a tail-less "jet" that attacked four (4) P-47s at near ground level. The "jet" would loop down and shoot and then loop back up again after each attack, repeating four times and downing ALL FOUR P-47s.
This plane that Joe described is certainly a Me-163. I have Mano Ziegler's book "Rocket Fighter", but there is no mention of this engagement. My father had the Me163C throttle-able motor in his possession after the war (at USAF Burtonwood, England), does anyone know if that plane was ever flown in Combat? This engagement sounds like the pilot may have had throttle control. I will post pic of C two orifice motor in the Spring when I get it from my Father.
