How do you know it's not lag?
There is a difference between how the jets move when there is lag, and how them shaking due to being in close vicinity of an explosian/shockwave.
Ive yet to experiance much lag, but when they DO lag, they move similier to how planes in AH move. they'll keep bouncing back& forth. or "Warping".
They did the same thing with the planes on 1943. That shaking is too smooth, along with the sound, to be from lag.
