I got the info from the 'Action Stations 3' book, which shows Tay Viscount VX217 at Seighford in front of its hangar. Apparently it flew from both there and Defford, investigating early fly-by-wire development (to quote the book - 'using electrical impulses to move the control surfaces').
VX217 was scrapped at Seighford in the early 60s.
The runway was 2000 feet long back then, but most is gone now. I've been in there several times in our Chipmunk, once as a bolthole from bad wx! Staffordshire Gliding Club now occupy the northern part of the site, operating off grass, but sveral hundred yards of the old runway still exists (or did when I was last there - quite a few years ago now).
