This list of "unknown" crash locations shows 7 Lancasters from the 26/27 Nov 1943 raid.
http://www.lancaster-archive.com/lan...crashsites.pdf
Included on the list is DV297. Not all of those listed actually seem to have 5 (or more) missing crewmen, but some others in that category are DV339 DS723 and DS679. These 4 are included in the appendix of Alan W Cooper's book "Bombers Over Berlin" which is about the RAF Berlin offensive from November 1943 to March 1944. The raid on 26/27 November was the 4th raid in the series of raids.
For the remaining planes of the seven on the list above, DV247 had only two men killed. DV268 had six men killed but they were buried in Sage War Cemetery. JB350 had five killed but they were buried in Berlin. Information on all these planes is according Cooper's book, so perhaps it needs to be verified elsewhere. Cooper does include the crew names.
