Jan Koum's Gulfstream G650ER, tail N143, departed Farnborough Airport in Hampshire, England, at 16:36 UTC on Friday, November 13, 2026, and landed at Van Nuys Airport in California 10 hours and 6 minutes later at 02:42 UTC.

The flight used about 63 percent of the aircraft's 7,500-nautical-mile range. Our estimate for this flight: about 4,749 US gallons of fuel burned and about 45,624 kilograms of CO2 emitted, roughly the same as driving a car 112,931 miles. The Gulfstream G650ER is an ultra-long-range jet with a top speed of Mach 0.925, a ceiling of 51,000 feet, and typically seats 12 passengers, up to 19.

This was the first landing at Van Nuys by one of Jan Koum's Gulfstream G650ERs in the tracked window from August 10 to November 10, 2026. Jan Koum's home base is Teterboro Airport in New Jersey, and his most common destinations in that window were Teterboro, Hartford, and Paris. In the 30 days before this flight, Jan Koum's three Gulfstream G650ERs flew 13 flights totaling 36.6 hours in the air, covering about 16,255 nautical miles and using 11 airports in 5 countries.

Jan Koum is the co-founder and former CEO of WhatsApp, a technology investor with a net worth of about $16.9 to 17 billion. He left Facebook and WhatsApp in 2018 over data privacy and monetization disputes. Van Nuys Airport is a major general aviation hub serving the Los Angeles area, and Koum owns extensive real estate in California, including a compound in Atherton and properties in Malibu and Beverly Hills. No scheduled public appearance or event tied to Koum was found in connection with this landing.

The aircraft is held by TVPX Aircraft Solutions Inc as trustee, an anonymizing owner trust. The FAA registry names no individual, so the attribution to Koum rests on reporting rather than on the registration itself. Koum's fleet includes two other Gulfstream G650ERs: N158 and N518KA.

The aircraft departed from Farnborough Airport, which has a longest runway of 8,005 feet at an elevation of 238 feet. It landed at Van Nuys Airport, where the longest runway is 8,001 feet at an elevation of 802 feet. The distance from Jan Koum's home base at Teterboro Airport to Van Nuys is 2,129 nautical miles.

Before this flight, the aircraft had been on the ground for about three days, following a previous tracked landing at Farnborough on November 10, 2026. In the 30 days before this flight, the longest leg flown by any of Koum's Gulfstream G650ERs was from Tel Aviv to Teterboro on October 26, 2026, covering 4,926 nautical miles.

This was a routine transatlantic crossing to a familiar destination, following a multi-leg journey through Europe and the Middle East.
