In Albert Speer's Inside the Third Reich, he states that he (Speer) was told by Flettner that Gauleiter Hanke of Breslau (Wroclaw), having conducted a ruthless defence of the besieged city, flew out in a prototype helicopter shortly before it capitulated.

IIRC there have been doubts raised about some aspects of Inside the Third Reich, but this has always struck as an intriguing reference to an early operational use of helicopters. Unfortunately it would seem difficult to check the story out with other references.
