Saw the airship flying over downtown Los Angeles on December 29th, 2010 at about 4:30 in the afternoon.
Realized immediately that this was no ordinary "blimp!"
Not a blimp at all, as it turns out!
This was something really "different!"
Spotted the tail propeller, but missed the side-mounted engines completely!
It appeared really, really long!
The gondola seemed to be quite far forward compared to ordinary "blimps!"
The ship disappeared behind a building and did not re-appear on the other side of the building. It must have turned to the north, and stayed hidden behind that building as it flew away.
