I was at Manby from Sep 70 - Sep 72 and was lucky enough to get a ride in one of the JPs in the Strubby close down formation flypast of the Lincs Air Force stations.
My log has the date of that flight as 20 July 1972 and the aircraft was XP688/22 flown by OC 3/4 Sqn, Sqn Ldr D.... G........
Apologies for the quality of the photo below but the print has not survived that well. It shows the JPs breaking away from the formation at the conclusion of the flypasts.
