Lancaster III, Serial JB471
At around 17.00 on 10 April 1944 the tranquillity of the Breconshire countryside was shattered when an Avro Lancaster III, Serial JB471, crashed into farmland at Cefn Gast, between Llanwrtyd Wells and Llangammarch Wells.
The aircraft belonged to a training unit, the Pathfinder Navigation Training Unit, which was based at RAF Warboys and trained crews to a high standard ready to join the elite Pathfinder Squadrons of the Royal Air Force.
Lancaster JB471 appears to have broken up mid-air before crashing out of control and bursting into flames, killing all eight men aboard, in a tragic accident witnessed by two local men stationed in a Royal Observer Corps post at Neuaddau Farm.
There is a memorial situated in St Cadmarch’s, Church, at Llangammarch Wells, to commemorate these eight men, as well as a number of other airmen killed in the area during the war.
