Elon Musk's JetLooks to be that Elon's jet is headed to Europe
You may notice that tracking is more sporadic. This is because ADS-B is ground-based, over the water we rely on ADS-C and ACARS, which is satellite-based. An example below is from one of the hobbyists that feed satellite signals to ADSBExchange. The one in the back has been picking up signals for the current flight, this is a California-based ground station. In about 2 hours we will be picking up a signal from the UK one.
Eric Gilmour@elonjet watch Musk try to stop this somehow with his starlink satellites
__Miguel_@erictgilmour @elonjet He could try, sure. But considering that ADS is mandatory for a rather large majority of airplanes, and interfering with those signals is a crime pretty much everywhere, well, let's just say I'd LOVE to see that happen :P
