I was in LUX and watched her come in. The first one had an immediate service bulliten, and went to the hangar to get four new engines. The second one came in yesterday, did touch and goes at HHN and MST. Last night it went to HKG. From what I have been told the aircraft is about 22,000lbs overweight. Also, the CG is nowhere near as good as the 400 and is coming in around 20% MAC. The new sweep on the wing is also a potential problem for loading oversized cargo as the K loader is now much closer to the wing. The military cannot use the 60K loader on the main door because of the 37 degree angle.
On the plus side, it is an extremely gorgeous airplane, and sounded like a 737 as it did its fly by.
