In my 'plane spotting days - early 60s - I remember being at Ringway, on the south side, one summer evening. An unusual call sign was heard on the wireless. 'Overhead in one minute', said the wireless. All binoculars all trained on the 24 approach.... nothing in view!? Then, exactly one minute later, a mighty earth shaking roar announced the arrival of a Vulcan - behind us from the south! It was low, and climbed away, as Vulcans do, with four smokey exhausts marking it's progress to the east. 'See you next month' said the wireless....
Happy days.
