RE: Jets and anhedral wings
No, your G-loading would be the same - the anhedral won't have any effect on the lift. You would notice a different dihedral / anhedral angle in flight though, as the wings will flex. Like a B-52 on the ground, the wheels on the wing tips are due to the "droop" - simply from weight the wing 'bends' or flexs down, and in flight up to some degree.
