Tango One

"Tango One" was the codename of a helicopter involved in the manhunt for the Third Doctor after General Finch and Whitaker framed him as the cause of the dinosaur appearances. When the occupants of one of the Jeeps pursuing him left their vehicle to search the surrounding woods, the Doctor used its radio to falsely report his own capture to Tango One who agreed to contact headquarters and call of the search.
