As NutLoose suggests, is there public support for restoration for a Cold War warrior of the 50s and 60s that was largely eclipsed by the V-bombers and mainly hidden from the British public from the 60s. I remember an excellent tight display by a T4 at Finningley probably in 1966. One particular manoeuvre was a half loop from low level, undercarriage lowered in the climb and rolling wings level from inverted flight at the top of the loop before landing. The majority of the crowd continued shopping, picnicking, or headed to the beer tent. In contrast the 4 Vulcan scramble silenced the crowd.
Much as NL would like to see the Sunderland or Gannet would they have any significance to most of the public?
