The flight was escorted by twelve other Fw 190s from Jagdgeschwader 26, ''Jagdgeschwader'' 26 under the command of Hans Dortenmann.
Having landed in Gatow, they changed planes to fly to the Reich Chancellery#New Reich Chancellery, Chancellery; however, their Fieseler Storch was hit by anti-aircraft fire over the Grunewald (forest), Grunewald. Greim was incapacitated by a bullet in the right foot, but Reitsch was able to reach the throttle and joystick to land on an improvised air strip in the Tiergarten (park), Tiergarten, near the Brandenburg Gate.

On 28 April, Hitler ordered Ritter von Greim to leave Berlin and had Reitsch fly him to Plön, so that he could arrest Heinrich Himmler on the charge of treason. That night, the two left Berlin, taking off from the Tiergarten air strip in a small Arado Ar 96 aircraft. Soldiers of the 3rd Shock Army (Soviet Union), Soviet 3rd Shock Army feared they had just seen Hitler escape. In a post-war interview, Reitsch said, "It was the blackest day when we could not die at our Führer's side."
Death

On 8 May, the same day as the surrender of Germany, Greim was captured by American troops in Austria. His initial statement to his captors was reportedly "I am the head of the ''Luftwaffe'', but I have no ''Luftwaffe''".
Greim committed suicide in prison in Salzburg on 24 May.
