Donald Robertson (writer)

Donald Robertson (22 August 1930 – 5 September 1995) was a Scottish engineer turned scriptwriter who penned four episodes of Thunderbirds: "Edge of Impact", "Desperate Intruder", "Danger at Ocean Deep" and "Path of Destruction". Usually his stories revolved around machines and vehicles in peril.

Robertson wrote his scripts in a caravan parked at the end of his garden in Birmingham, finding it peaceful and quiet. His other TV work seemingly included Dr. Finlay's Casebook and Crossroads.
