This confuses the issue though. 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 and if an aircraft was going to takeoff that had an unknown ICAO number he'd have someone at the airport to figure out it was Elon's jet that had changed it's ICAO number.
Your link will only be valid until he again changes his ICAO number.
