> ICAO numbers change if your aircraft is enrolled in the PIA program, which Elon is. Sweeny was bypassing this by using people on the ground to circumvent this by watching the jet's movement

Maybe he should just buy another jet or two, make sure the other jet(s) are in regular use (maybe shuttling SpaceX/Tesla/Twitter/etc employees around), and make sure he regularly swaps which one he is personally using. Extremely expensive solution, but not beyond his budget.

Or maybe he should just buy himself a private jet chartering firm. An even more expensive solution, but he can probably afford that too.
