Service records?

I'm looking for information on a Luftwaffe Pilt (Fltt Lt?_ Arthur Friederich Angellotte-mackensen. Last know flying JU52's out of Berlin late in April 1945.

Also on Flt Kpt Peter Erich Baumgart Awarded Knight’s cross 31/7/1943 and also allegedly with 128 kills over crete, Italy, North Africa and in the East.
Again possibly flying Ju52 out of Berlin late in April 1945 from Hohenzollerndamm.
Does anyone have any idea if this part of berlin had an Luftwaffe airfield, even a temporary one in April 1945?
