Gulfstream G550
N18S · ICAO: A13FE3 · Heavy jet

Stuart Sloan ran Schuck's Auto Supply before taking over Quality Food Centers with Jack Croco in 1986, taking it public in 1987, pushing it up-market against the regional chains and selling it to Fred Meyer for $1.7B in 1998. He co-founded Egghead Software, runs Sloan Capital Companies, and owns University Village — the open-air shopping center in northeast Seattle that is among the highest-grossing retail properties per square foot in the country. He lives in Denny Blaine. No reliable current net-worth figure is published, and the ones that circulate are artifacts of stock-disclosure scrapers rather than real estimates.
His philanthropy has been unusually concentrated. From 1998 he committed around $1M a year for at least eight years to a single Seattle public school, T.T. Minor Elementary — class sizes down to twenty, free pre-K, meals, healthcare, teaching assistants — reported at the time as the largest single gift ever made to an American public school. Scores rose after 2001; the district closed the school in 2009 on cost grounds anyway. In 2022 he and his wife gave $78M to the Fred Hutchinson Cancer Center, the largest gift the institution had received.
He was also, as KUOW revealed in May 2024, the anonymous $550,000 donor behind a proposed playground at Denny Blaine Park — a long-established nude beach next to his house. The Stranger later reported he had sent photographs of unconsenting beachgoers to city officials including the mayor. The plan was abandoned.
He does not sit for photographs. A 2013 Seattle Times profile records that he declined to be photographed for it, and KUOW's 2024 piece stated flatly that no pictures of him could be found online. The portrait here is from QFC's own 1989 annual report — a studio group shot of the four executives with each man's signature printed beneath him, which is why it can be attributed with certainty. He was about 46. It appears to be the only published photograph of him in circulation.
N18S is a 2015 Gulfstream G550, serial 5531, hex A13FE3, registered to 5531 LLC at an address in northeast Seattle — the LLC is named after the airframe's serial number, which is a tidy piece of registry housekeeping and also the only reason the two are obviously the same thing. Spotted at Boeing Field. No press has ever tied Sloan to it by name.
Note · We track Stuart Sloan's planes, not Stuart Sloan in person. Flight data shows when and where each plane flew. It does not show who was on board.
We do not see it in the air right now. The last flight we tracked for Stuart Sloan's Gulfstream G550 (N18S) landed at Seattle Paine Field International Airport (KPAE) on October 3, 2026. Follow it on the live jet tracker map.
The map shows where Stuart Sloan's plane has flown. Each dot is a recorded position.
Over the last 2 completed flights we tracked, Stuart Sloan's private jet spent about 3 hours in the air. We estimate those flights put out 12.0 metric tons of CO₂.

Owner matches come from the FAA registry, adsb.lol (ODbL) and ADSB.fi data, and SEC filings. They may be incomplete or out of date. Methodology · Report an error. For observational use only.
About 4,131 kg for every hour in the air. Stuart Sloan's Gulfstream G550 (N18S) burns roughly 430 gallons of jet fuel an hour. That is about the same CO₂ as driving an average car 10,225 miles.
Stuart Sloan's home airport is King County Intl / Boeing Field (KBFI / BFI). Frequent stops include KPSP, KSNA, KVNY and KSUN.
About 12.0 metric tons of CO₂ over 2 tracked flights and 3 hours in the air. We start with the flight times from public ADS-B data. We multiply each hour by the maker's fuel burn figure. Then we apply the EPA standard of 9.57 kg of CO₂ per gallon of jet fuel.
Yes. The FAA requires planes with transponders to broadcast their position over ADS-B, and the signal is not encrypted. We collect that public data from adsb.lol and ADSB.fi, two open flight-tracking networks. News outlets and university researchers use the same kind of data. Our methodology page explains how it works.
