If I remember correctly 1983 was the year of the tribute to Sir Douglas Bader and Lady Bader paid the objects at the "Peace" Camp a visit asking them if they would not disrupt the show as her late husband had fought for people like them to be able to have their protests. However as seen by the paint attack they did not have the decency to keep their word. The SR-71 stayed a couple of days after the show departing on the tuesday or wednesday although I did have the pleasure of seeing it heading over my garden after take-off.
