Assignment: Earth was the twenty sixth episode of Star Trek’s second season to air, with an intergalactic secret agent battling to stop a twentieth century nuclear holocaust. In this episode Gerry and Iain discussed the appropriate clothing for time travellers.
On a mission to observe a key period of Earth history, the Enterprise intercepts Gary Seven (Robert Lansing) and his cat Isis as they attempt to travel to the planet from a distant world. Seven makes his escape and heads to the United States where a critical weapons launch is due to take place.
Despite interference from Seven’s secretary Roberta Lincoln (Terri Garr), Kirk and Spock make it to the launch site where they are waylaid by Launch Commander Cromwell (Don Keefer) and others as they attempt to stop the sabotage Seven says is vital to Earth’s survival.
In this episode Gerry and Iain considered the wisdom of using your fountain pen as a secret switch.
