Talking about the North Sea, I attended the ACA meeting & was able to film Arthur Creighten, who was also Nav Rad but on Valiant's. He described how they did high altitude Maritime Reconnaissance missions flying up the North Sea, Artic Ocean & Barents Sea towards Murmansk. They had a camera in the bomb bay, also a 35mm camera taking a photograph every sweep of the H2S P.P.I. If they saw anything unusual, the USAF would send a low level aircraft from Greenland to investigate. On a lot of sorties, they would be accompanied by a Canberra flying at low level.
