Fascinating thread for many reasons, names, places, aircraft......
Per AL R's pics I attended that airshow at the tender age of sixteen with big bro and remember the ominous skies as captured in his pics. Mine were the same. Must dig out my old kodachromes and post.
I do recall that there was a TR-1 at that airshow and being surprised at the noise of its departure.
"Operational TR-1A's were used by the 17th Reconnaissance Wing, Royal Air Force Station Alconbury, England, starting in February 1983."
