Nobody has mentioned, that XK695, was originally a B.O.A.C. aircraft, registered as G-GAPY (I think, I've lost my records) and which finished its flying life on 51 Squadron at Wyton. XK659, XK655 and XK671 were also on the squadron (I may have the prefix letters wrong, but the numbers are correct).
I remember, that during servicing, the B.O.A.C registration was clearly marked in many inaccessible areas of all four Comets. Flew in all of them many times.
