What kind of drone was that?

Rating: 7/10 (21 May 2006)

I liked the movie but that's probably because I'm easily pleased.
But anyway, could anyone tell me what kind of drone that was? I get the feeling that they simply came up with their own and modeled it after the Predator B, or the Global Hawk. I saw a few major similarities between the one in the movie and the two I just mentioned.
The similarities I found were: 1. The movie drone, the Predator and the Global Hawk all have very long wing spans. 2. The movie drone, the Predator B (not A) and the Global Hawk all have 2 upward, diagonal tail fins. 3. The movie drone and the Global Hawk have jet engines. 4. The movie drone looked like it had the "bulb" nose (where the cockpit would normally be) and the Predator B also has a "bulb" nose. (The Global Hawk has more of a swan like shaped front).
One major difference I saw was that I thought I saw a frame where they changed the drones flight pattern by using something that looked like a PDA. The Predator is flown via a Ground Control Station. I don't know what tool they use to fly the Global Hawk but I assume it's similar to the Predator's GCS, although it is completely autonomous. So the PDA idea may be feasible, I guess.
What do you guys think?
