As part of Casualty Communique No. 224, the crew of Lancaster ED559 are recorded as Missing in the 29 April 1943 edition of Flight magazine.
In the 27 Januay, 1944 edition of the same magazine, Casualty Communique No. 335, mentions the crew as now "Previously Reported Missing, Now Presumed Killed in Action."
As and when information is found I'll post to this blog.
