Mark Stevens's Gulfstream G600 N408SB flies from Los Angeles to Las Vegas in 49 minutes

Mark Stevens's Gulfstream G600, tail number N408SB, flew from Los Angeles International Airport to Harry Reid International Airport in Las Vegas on Sunday, November 15, 2026. The aircraft departed at 19:18 UTC and landed at 20:07 UTC, spending 49 minutes in the air. The flight covered a great-circle distance of 205 nautical miles, or 236 miles.

Los Angeles International Airport has a longest runway of 12,894 feet and sits at an elevation of 125 feet. Harry Reid International Airport has a longest runway of 14,835 feet and an elevation of 2,181 feet. The distance from the aircraft's home base at Yampa Valley Airport to Las Vegas is 457 nautical miles.

The Gulfstream G600 is an ultra long range jet with a top speed of Mach 0.925 and a ceiling of 51,000 feet. On this trip, the aircraft reached a highest altitude of 25,000 feet and a top ground speed of 463 knots. The average ground speed was 253 knots. Celebplanes estimates the flight burned about 357 US gallons of fuel and produced about 3,430 kilograms of CO2, roughly the same as driving a car 8,489 miles. The aircraft can seat up to 19 passengers and fly 6,600 nautical miles without stopping, so this flight used about 3 percent of its range.

Before this flight, N408SB had not landed at Las Vegas in the tracked window of the previous 30 days. Its home base on file is Yampa Valley Airport in Hayden, Colorado, and its usual destinations include Seattle's Boeing Field and San Jose's Norman Y. Mineta International Airport. In the 30 days before this flight, the aircraft made 7 trips totaling 11.3 hours in the air. Two other tracked aircraft landed at Las Vegas in the 24 hours before this landing: an Embraer Legacy 500 linked to MGM Resorts about 21 hours earlier, and a Bombardier Challenger 604 linked to Vinod Khosla about 18 hours earlier.

In the 30 days before this flight, the aircraft visited four airports and flew about 4,242 nautical miles. Its most common destinations were Seattle's Boeing Field and Los Angeles International, each with two landings. The longest leg in that period was from Seattle to Hayden on November 9, covering 737 nautical miles. The aircraft had been on the ground for about three days before this trip, after landing at Los Angeles on November 12.

Mark Stevens spent more than two decades as a partner at Sequoia Capital, where he was a managing partner and sat on boards including Nvidia's. He now invests through his family office, S-Cubed Capital. He is a minority owner of the Golden State Warriors and in September 2026 became the largest minority investor in the Seattle Seahawks, behind only the Khosla family, in the $9.612 billion purchase of the team from the Paul G. Allen estate. No public events or games involving Stevens or his teams were scheduled in Las Vegas on the day of this flight.

Another tracked aircraft, a Bombardier Challenger 650 linked to Boston Scientific, landed at Las Vegas under an hour before N408SB. The Gulfstream G600 is a stretched version of the G500 and has four passenger zones. Celebplanes estimates the aircraft burns about 440 US gallons of fuel per hour.

The aircraft, a 2025 model with serial number 73185, is registered to Lets Go Now LLC at an Apres Ski Way address in Steamboat Springs, Colorado. The FAA lists the LLC as the owner, and the tie to Stevens is through the LLC's ownership rather than the registry itself. The Yampa Valley base is read off the Steamboat registry address, not observed; Bay Area fields and Boeing Field on game days are the likelier pattern.
