Interplanetary Pursuit
From Tardis Wiki, the free Doctor Who reference
The Interplanetary Pursuit was an Earth paramilitary force, organised in squadrons.
The A Squadron was charged with the recovery of two kidnapped Earth children. During the mission, their ship was attacked, then crashed on the asteroid Titan III. Lieutenant Hugo Lang was the only survivor, who later helped the Sixth Doctor to accomplish the rescue. (TV: The Twin Dilemma)
