Watched an early August 2020 Mark Felton documentary last night; which is summarised as: Link: I have never heard of 'black Lancasters', the name came from their colour scheme; nor such a possible deployment. Or the development of inflight refueling from January 1944, with test flights in November 1944; one photo shows one plane bears G-ARJW (no trace Google as used on a Lancaster), the other cannot be read. Range was increased to 2,530 miles. Mark Felton provides the historical background, including technology and refers to six bombers with no markings going in 1943 to RAF Enstone, a satellite field for Moreton-in-the-Marsh, where No. 21 OCU was based and the planes being kept in closed hangars, with the crews isolated. He claims: Background: Enstone Airfield — Classic Flight Ltd and Enstone Airfield - Wikipedia He also refers to Tiger Force, a RAF bomber command, being prepared and mentions the 'black bombers' would use an airfield in Burma, the name sounds like Kinion. If the RAF had been needed it is obvious they would have flown to a USAAF airfield, such as Tinian where the atomic bombs were delivered. See: Tinian - Wikipedia There are a mass of comments and some unverified information, such as: Interred? Confined to barracks better. I had forgotten over Hiroshima there were two British observers, the scientist William Penney and: I had a look last night for supporting information, to be fair there is very little. This 2014 website passage supports his account: Link: Project Silverplate Our part was small, but vital: Ironically I recalled this: Link: Boeing B-29 Superfortress - Wikipedia I would be interested in the Forum's thoughts and if any evidence exists that supports his story. Alas he provides no sources.
