Could anyone please give me anymore details about the loss of this aircraft and the names of it's crew? Where did it start its operation from and was the cause of its loss ever determined?

Such happy endings were not to be in November. Aircraft unserviceabilities born of progressive equipment deterioration were occurring more frequently, seeing four of twelve squadron aircraft undergoing major overhauls. 31 Out of those aircraft flying, one-half either crashed or were damaged by the end of the month.
The first accident occurred on Remembrance Day. F/L M.D. Lee and crew departed Lough Erne in 3+D (DP181) in mid-afternoon, only to be recalled by weather. The aircraft crashed on landing, killing five and wounding the remaining six crew members.
Two days later, F/L A.F. Brazenor and crew took off in 3+J (DD863) for an anti-submarine patrol. Two hours into the mission, the aircraft reported it was returning due to engine trouble. Soon afterwards, it sent an S.O.S., giving its position as fifteen miles from the coast. The aircraft disappeared. Five days later, wreckage identified as parts of a Sunderland was washed ashore in the vicinity of the last report. All twelve men were lost.
