MOUNT BRANDON, IRELAND. At 04.30 a.m. on July 28 1943 while circling in dense fog the Short Sunderland flying boat on it’s way from Lagos, Nigeria, to Poole, via Lisbon, crashed into Mount Brandon near Slieveglas on the Dingle Peninsular, Co. Derry, killing ten crew and passengers. The majority of the mail being carried was from P.O.W.’s in Japanese camps, but a small amount of civilian mail from West Africa was also on board.
