Chameleon Tours

In 1966, Chameleon Tours was marketed as a Gatwick Airport-based business offering budget package holidays to Europe for young people between the ages of 18 and 25.

History
Chameleon Tours was actually a front for the Chameleons, who abducted the humans, took them in aeroplanes to their space station, then miniaturised and placed them in suspended animation. Samantha Briggs hired Inspector Gascoigne to investigate them when her brother Brian went on a Chameleon Tours trip to Rome and disappeared.

The Second Doctor and Jamie McCrimmon helped her and exposed the Chameleons' operation. (TV: The Faceless Ones)
