New He 219 Book from Wingleader.

[FalkeEins]

the technical development of a new type is intricately bound up with its combat history (how many marks of Spitfire were there- the Montforton book only analyses the engineering of the IX and XVI..) ...and especially with a machine like the He 219. After a combat debut in early June 1943 - during which five Lancasters were claimed - six months later in December 1943 I./NJG 1 still only had three serviceable He 219s on strength..page 109 of Ron Ferguson's book looks at the work of the 'Heinkel Technical field Service Unit' at Venlo and considers the many (many, many..) problems affecting He 219 serviceability..
