ALF's spaceship crashes into the Tanner Family's garage after Melmac explodes. ALF narrowly misses planet Alvin on his approach to Earth. ALF's spaceship contains gold plumbing, which he later sells to purchase a Ferarri.
His spaceship was borrowed for a science-fiction movie called Jupiter Guys in The Gambler, and the Tanners were paid $6,000 for it.
ALF said in the pilot episode he cannot drive it, but in the animated cartoon, he is shown driving the spaceship perfectly. In Baby, You Can Drive My Car, ALF cannot drive a car, but in Come Fly With Me, he show that his knowledge of spaceship piloting is sufficient for him to figure out how to fly a plane.
Willie Tanner was able to pick up the radio signals from ALF's spaceship, and ALF was perhaps speaking in Melmacian language. ALF's spaceship's sound wave transmissions could not be shut off by Willie's radio station. ALF apparently has been used during the Third Galactic War, which ended Melmac, due to the nuclear outfittings on his weaponry, caused by the Second War.
