If you'd wanted to join these passengers and stow away on-board this Lockheed Constellation airliner, all you had to do was climb over the chain-link fence.
Designed during the Second World War, as the first pressurised airliner in widespread use, the Constellation helped to usher in affordable and comfortable air travel. Mind you, it wasn't cheap to fly, meaning most of the passengers touching down in Scotland were wealthy American visitors.
In October 1948, a KLM Constellation, en-route from Amsterdam to New York, crashed near Prestwick, killing all 40 people on board.
With the advent of jet planes, the last passenger Constellation took flight in May 1967.
