N502SX, a 2004 Gulfstream 5, owned by FALCON LANDING LLC. Looks like Elon musk is flying from Starbase to the cape. Flight track looks a little southerly, but there is weather ahead. Who knows? Could be flying to the Bahamas for all anon, or flight aware knows. This aircraft does not hide flight plans on flight aware either. Try an image search for the tail number. Spoopy. Nah. Brand new certificate for that tail number issued 09/08/2021.
N74VW, also a 2004 Gukfstream 5, owned by EARTHSHIP LLC. This is Nicholas Woodman. Founder, CEO and Chairman, GoPro.
