Mark Zuckerberg's G700 lands at Moffett the morning after his monopoly-trial testimony

A Gulfstream G700 operated for Mark Zuckerberg's trust touched down at Moffett Federal Airfield at 03:44 UTC on August 26, completing a 20-minute hop from Monterey Regional. The aircraft, N3880 — delivered new to the fleet in December 2024 and painted in Meta's blue-and-white livery — flew a track that never exceeded 5,950 feet, a pattern consistent with a local positioning move rather than a cross-continent mission. The flight followed a longer journey on August 14, when the same aircraft tracked from Savannah (KSAV) to Monterey via a fuel stop, before continuing to Juneau and Anchorage, where it spent six days.

If Mark Zuckerberg was aboard the G700 for this short leg, the timing would place him back in the Bay Area the same week his public testimony in the Federal Trade Commission's monopoly trial continues to reverberate through antitrust circles. As Ars Technica reported in April 2025, Zuckerberg testified that "the amount that people are sharing with friends on Facebook, especially, has been declining," arguing that TikTok, not Facebook or Instagram, is the dominant competitor in a market now defined by "discovery engines" rather than personal social networking. The judge, U.S. District Judge Amit Mehta, had earlier ruled that Meta holds a monopoly in personal social networking, and Zuckerberg's testimony seemed aimed at softening that definition. The trial's second phase — remedies — is unfolding this summer, and any return to California could signal preparation for a settlement push or further depositions. Meta has publicly declared a focus on reviving "OG Facebook" with a new Friends tab, while simultaneously introducing a "blend" feature for shared discovery algorithms — a dual strategy that the FTC's lawyers have reportedly characterized as an attempt to have it both ways.
