Mark Zuckerberg (Meta Platforms) flies a Gulfstream G650ER · G700 registered on the tails N68885, N3880. This page follows those registrations on a live map with the current leg, altitude and a per-flight carbon estimate.
The globe above draws the current simulated leg for Mark Zuckerberg's registered aircraft between its typical city pairs, with KSJC as the home base. Because the live ADS-B feed for most high-profile tails is blocked at the owner's request (the FAA's LADD programme and its international equivalents), the positions shown are reconstructed from documented tail numbers, published travel reporting and typical routing — not a real-time transponder read.
The carbon figure beside each leg estimates fuel burn for the Gulfstream G650ER · G700 over the great-circle distance of that route, using standard per-hour burn rates for the airframe class. It is an order-of-magnitude figure meant for comparison between subjects, not a metered measurement.
Registration data is compiled from public civil aircraft registries and open planespotting records. If a tail is sold or re-registered, the board keeps the historical record rather than silently rewriting it.
