Jan Koum's Gulfstream G650ER N143 flies Teterboro to Paris in 6 hours 32 minutes

Jan Koum's Gulfstream G650ER, tail N143, departed Teterboro Airport at 17:27 UTC on Sunday, November 8, 2026, and landed at Paris-Le Bourget International Airport 6 hours and 32 minutes later at 00:00 UTC. The short hop covered a great-circle distance of 3,150 nautical miles, or 3,625 miles, at an average ground speed of 482 knots. The aircraft reached a highest altitude of 45,050 feet and a top ground speed of 573 knots.

The flight used about 42 percent of the aircraft's 7,500-nautical-mile range. Our estimate for this flight: about 3,074 US gallons of fuel burned and about 29,528 kilograms of CO2 emitted, roughly the same as driving a car 73,089 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 fourth landing at Paris-Le Bourget by one of Jan Koum's Gulfstream G650ERs in the tracked window from August 7 to November 8, 2026. The previous landing at the same airport occurred on October 18, 2026, 21 days before this flight, by N143. Jan Koum's home base is Teterboro Airport in New Jersey, and his most common destinations in the tracked window were Teterboro, Hartford, and San Jose. The aircraft spent about 1 hour on the ground at Teterboro before this flight, following its previous tracked landing there earlier on November 8. In the 30 days before this flight, Jan Koum's three Gulfstream G650ERs flew 14 flights totaling 40.3 hours in the air, covering about 18,044 nautical miles and using 10 airports in 4 countries. The longest leg in that period was a 4,926-nautical-mile flight from Tel Aviv to Teterboro on October 26, 2026, flown by N143. Two other tracked aircraft landed at Paris-Le Bourget in the 24 hours before this landing: Andrew Forrest's Bombardier Global 8000 about 11 hours earlier, and Gang Ye's Gulfstream G650ER about 6 hours earlier.

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. Paris is a regular destination for Koum's fleet, and the aircraft arrived at Le Bourget, the primary business aviation airport serving the city. 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.

Teterboro's longest runway is 6,997 feet at an elevation of 9 feet. Paris-Le Bourget's longest runway is 9,843 feet at an elevation of 218 feet. The flight burned an estimated 470 US gallons of fuel per hour.

This was a routine transatlantic crossing to a familiar destination, following a short turnaround at Teterboro.
