WILLIAMS, M.W. - Originally from New Zealand. Looking for the relatives of the late Sub-Lieutenant (A) M.W.WILLIAMS (RNZNVR) killed 28 May 1944 while serving at HMS Ringtail.

He was making a camera attack on a target at 3000 feet when his Firefly spun off at a tight turn, recovered, spun off in the opposite direction and crashed at Holmeswood about eight miles from the airfield. Please contact Haydn Taylor, 2 Belmont Ave, Clifton, Swinton, Greater Manchester, M27 6WL, England. (The Greater Manchester Branch of the Fleet Air Arm Association.) Thank you. Posted 30 Jun 1998.
