Just discovered that WZ557 was with 16 Sqn at Celle 10 Sep 53 to 7 May 54 and was sent Cat 4 to Marshalls for repair.Later served with 5 FTS at Oakington. Not sure why she was damaged by on another site there is a comment that she was involved in a tragic accident where a fitter set off one of the ejection seats (date location not known). Any ideas on that incident? Also does anyone have any idea of an aircraft letter for her whilst with 16 Sqn?
