“April 18th/19th 1944 – Junkers Ju188E-1, (Werk Number 260391), coded U5 + BN, of 5/KG2 Hit at 18,000ft by 3.7 ins AA fire from Gun Sites E1 (Chadwell Heath), E9 (Wanstead) and W1 (Enfield). Crashed into Number 14, Seven Kings Road, Ilford, Essex at 0118am.

Four occupants at 14, Seven Kings Road, were killed in the incident – fuel from the crashed Ju188 ignited in their cellar shelter, where they were burned to death. They were Mr & Mrs Edwin Foyster, Mrs Winnifred Lee and Miss Stella Palmer.

Hope this helps? I’m sure other forumites will point you in the right direction when it comes to establishing the final fates of the surviving crew?
