Interesting re. the date ('56) and the total disappearance of the aircraft. It was around this time that a) a Valetta out of one of the Canal Zone airfields (Abu Sueir?) folded its wings in turbulence and b) all our Squadron aircraft were grounded and found to have spar cracks and wrinkled mainplane skins on 12 out of the 14. Particularly interesting in that (apparently) the civil version had had spar plates incorporated some time previously as the problem was known about.
