In 2277, a recon craft, designated as Theta, was on a mission to Earth. The ship crashed in the Capital Wasteland, north of Minefield and northwest of Greener Pastures disposal site, leaving the vehicle heavily damaged and the pilot dead. Sometime later, the crashed recon craft began broadcasting a radio signal, the Recon craft Theta beacon. Once the Lone Wanderer approaches the ship for inspection, they are immediately abducted by MothershipZeta. At the same time of the abduction, Theta is beamed up by MothershipZeta and stored in the vessel's hangar bays.
An unnamed recon craft can also be found at the crashed alien ship in Fallout: New Vegas, though this craft is occupied by three alien passengers rather than one.
