Night Bombers - 1943 - amazing colour video of RAF No. 1 Group Lancaster raid on Berlin during early 1944

 from PJ Clarke's review;

 "..The documentary, 'Night Bombers,'is an absolute must for any person interested in RAF Bomber Command's activities in 1943-4. The documentary was made during the war, using colour film. It is believed to be the only colour film made during WW2 concerning the RAF. For that reason alone, it is worth it's weight in gold. It focuses on the preparation & planning behind a raid on Berlin, by Lancasters from No 1 Group. Seeing the RAF Lancasters, the ground crews & aircrew engaged in their respective daily activities is fascinating. The documentary brings home to the viewer the tremendous human effort that went into the bombing campaign. There is much to commend this film, from the scene of a Lancaster undergoing an engine change, to the work of the armourers as they bomb up Lancaster 'V'- Victor. From an historical point of view, this film is of major significance, being the sole documentary of it's type to have been made during the conflict. It includes the collation of weather reports and the briefing of aircrew prior to the raid. The scene of 'V' under full power of four growling Rolls Royce Merlins on take off, is sufficient to make the hairs stand up on the back of any aviation buff's neck. ..."
