Charles Simonyi led the teams that built Microsoft Word and Excel after bringing WYSIWYG editing with him from Xerox PARC, where he had written Bravo. He left Microsoft in 2002 to found Intentional Software, which Microsoft bought back in 2017. He flew to the International Space Station as a spaceflight participant twice, in April 2007 and again in March 2009 — the only private citizen to make the trip twice — and the Simonyi Fund for Arts and Sciences has given to the Institute for Advanced Study, the Seattle Symphony and the Charles Simonyi Endowment for the Public Understanding of Science at Oxford.
N822LC is registered to Valkyrie 8X LLC of Seattle. There is a wrinkle worth stating: the FAA MASTER row carries the model as FALCON 7X, because Dassault certified the 8X as a derivative on the 7X type certificate, but the airframe is a Falcon 8X — S/N 492, built 2022 — and Flightradar24 and AirNav Radar both report it under ICAO type FA8X. This roster follows the airframe, so it is filed as an 8X and the poller matches on FA8X. A registry search on model alone will disagree.
The LLC name is the attribution. Valkyrie 8X LLC holds this jet the way Valkyrie 7X LLC held the Falcon 7X N786CS before it — an entity named for the aircraft type rather than the owner, which is a deliberate privacy pattern and not a registry confirmation of the person. Base is Boeing Field.
