Relatives would very much like contact with one another - all have a story to be told - whether they survived the war or not - many memorials and pages on the internet tell the stories of those who lost their lives - so many more exist for those who came through the war, their stories never told! The original crew of F/O. James Hubert Mason DFC went on to carry out further operations - some lost their lives at a later date, others survived. We are working on further pages to the crew of F/O. James Mason and his previous operations.


Taking off from RAF Swinderby in Lincolnshire on a night exercise, the crew, including pupil pilot and two flight engineers. At 21:32 hrs, soon after departing, the Stirling came down at Carlton-le-Moorland, 9 miles SSW from Lincoln.

The three injured airmen succumbed to their injuries on the following day.

We don’t have details as to the cause of the crash and welcome any new information.
