Pilot information requested

I'm looking for information on a Luftwaffe Pilot (Flt Lt?_ Arthur Friederich Angellotte-Mackensen. Last known 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 a Luftwaffe airfield, even a temporary one in April 1945? And what unit might have been flying out of it?

Please reply to williamsgerrard@hotmail.com

Many thanks
