79. Little Green Men
Summary
Nog has been accepted to Starfleet Academy and is about to leave the station for Earth, as Quark finally gets the ship his cousin Gaila promised him. With Rom piloting, the Ferengi family heads for Earth; but Quark is smuggling kemacite, which causes the sabotaged ship to go back in time, to 1947 on Earth, crashlanding in Roswell, New Mexico. The three find themselves being studied by suspicious US Army officers. Quark decides to rule Earth with advanced technology, timeline or no timeline; but Odo, a stowaway, opposes him. Finally, with the aid of a sympathetic nurse and her fiance, they escape and are able to reach their own time period.
