JAJ,
This looked like a recently produced programme and I thought it did a good job of recounting the events
Definitely recently produced as Phil Tetlow (WOP/AG from 9 Sqn), the guy with the sense of humour, was just recounting his Tirpitz experiences, and the filming, to us at last month's ACA meeting in Nottingham. Unfortunately, the edit cut out the bit about the landing conditions when the Lancs arrived at the FOB in Russia before the first raid. Evidently horrendous, many aircraft did not 'make it' and many were forced to turn back and/or seek an alternative landing site. So not quite as portrayed by Channel 4 but a good documentary nonetheless.
