I saw a very large, dark gray triangular shaped object in daylight, which was not identifiable.

This sighting of a strange aircraft was witnessed by myself and one other unidentifiable person. It was a very brilliant sunny day. The giant aircraft was seen floating over the Davis-Monthan AFB, but maybe to the west, near the Tucson Airport. It was very large. My guess is that it was about 2 city blocks long. It was dark gray or black. There were no markings on it (and no lights , since it was daylight). It hovered for a few minutes, very silently, and "tipped" it's wing slightly, so I saw the dimension of its size.It suddenly disappearred, as if it was never there.  It was not a civilian aircraft, or any USAF jet, since I'm familiar with all those due to living in the area. This craft was gigantic. this is no hoax, and I only report it now due to much embarrassment when I tried to tell others about it many years ago.
Date is approximate.  NUFORC received the same report from the same party on January 02, 2002.  PD
