Gannet AEW.3 XJ440 over Ringway.
The Gannet is over Farnborough, not Ringway! Never believe captions, especially when Manchester Airport has acquired a balloon shed...

The photograph from Peter Amos shows the BSE test flight in the late 1950s. On the right is a Sabre and the serial can be discerned as XB962! As this does not appear as a RAF aircraft it would appear that an additional Sabre was delivered and did not get taken on charge by the RAF. If so, what was its previous identity? And what did BSE do with XB900?
Also in the photo are Gnat F.1 XK740 and a Fiat G-91 with '12' on the nosewheel door. Two G-91s were used by BSE. G-45-3, ex-MM6285, was returned to Italy and became G-91R 5-285. The other was G-45-4, ex-6246, which returned to Italy and crashed at Treviso on 15 February 1965. This is presumed to be the one in the photograph.

Meteor F.8 WL117 served with Nos.19 and 72 Squadrons. So what are the curious markings shown in the photograph?
The consensus of opinion nails it down to the Armament Practice Station, Acklington which had a number of Meteors so marked.
