A friend of mine who is an Air Britain member supplied the following details which may be of use ? ;
1.7.44: 455Sqn (Langham) Beaufighter NE773, which took off at 1600hrs, lost starboard engine and aircraft spun into the ground, Cley-next-the-Sea, Norfolk, 5 miles from base, during formation practice and local flying.
2114 Flg Off (Plt) John Urban Billing, RAAF, 28. Son of Urban Stanley Billing and Louisa Ann Billing, of Mildura, Victoria. Grave 13506.
426574 Flg Off (Nav/W.Op) Terence Oliver Edwards, RAAF, 20. Son of Ernest Edward Edwards and Julia Edwards, of Auchenflower, Queensland. Grave 13706.
(Had these Australians been killed in Somerset I would have expected them to be buried at the RAF Regional Cemetery at Bath.)
