sorry Rod-

from wikipedia:

The movie has been revised and re-edited numerous times, notably for a 132-minute "Special Edition" reissue in 1980 and again for a 137-minute "Collector's Edition" in 1998 (see List of films recut by studio for details on these alternate versions).
The Special Edition features several new character development scenes, the discovery of a lost ship, the SS Cotopaxi, in the Gobi Desert, and a view of the inside of the mother ship. The interior of the mother ship is deleted from the "Collector's Edition". (Spielberg added this scene as a concession to be allowed to make the Special Edition. He decided it was a mistake and removed it in the later edition.)
