Well... I tried to test your mission, but it said I was missing "addon tmf_117" and wouldn't let me load the mission, so I couldn't test that part. I managed to test your aircraft a little bit and here are some things I found immediately:
1. The texturing needs to be changed, it isn't that attractive.
2. In real life, a Global Hawk isn't that "fat", it is more long and narrow.
3. When I put the gear up, the front hear was retracted but was floating 5 feet below the aircraft all the time.
4. In real life, the global hawk's rear aerial fins are pointed in a downward V, not a regular V. That is what separates it from the predator.
Nice concept though, keep working.
