Above sentence is incorrect:- The last wartime operation by No. 420 Squadron was to Bremen on 22 April 1945. This was to be an army co-operation raid but heavy cloud prevented accurate bombing and the operation was cancelled by the Master-bomber. Most aircraft including mine dropped their bombs safely in the North Sea.


In 2004 the Canadian Broadcasting Corporation made a film which documents the crash of DF626, a Wellington bomber of the 420 Squadron. The film is called "Final Flight, The Search for DF626"
