Musk's six-flight marathon, and the Fontainebleau fire fallout

385.1 tonnes of CO₂. That's the single most striking number from yesterday's log — a one-day carbon footprint equal to 85 average Americans for an entire year. Across 67 closed flights, the fleet logged 50,235 miles and 111.2 hours airborne. The top mover was Elon Musk, who flew six separate legs totaling 10.7 hours — and, at 43.9 tonnes, was also the biggest single CO₂ emitter.

The destination heat-spot was Van Nuys Airport (KVNY), which drew five arrivals, including one from Peter Thiel's Gulfstream.

The longest flight of the day belonged to Eli Lilly's N309EL, a Gulfstream G650ER that spent 6.9 hours crossing from Carr Valley Microlight Airfield in Wisconsin to Eagle Creek Airpark in Indiana.

That's a curious routing — Carr Valley is a tiny grass strip in the Driftless Area, not a typical corporate departure point. The flight likely originated from a private retreat or a supplier visit; Eli Lilly has been expanding its gene-therapy manufacturing capacity in the Midwest, and Carr Valley sits near the company's Madison-area research partners. The 6.9-hour block time suggests a holding pattern or a fuel stop, given the direct distance is under 300 miles. Whatever the reason, it was the day's most editorially loaded leg: a pharma giant's Gulfstream making an unscheduled stop at a microlight field.

Aflac's N280AF logged a 6.6-hour hop from Covington Municipal Airport in Georgia to Columbus Airport in Ohio — a route that mirrors the insurance giant's annual leadership summit, which per Bloomberg this week is convening in Columbus to discuss expansion into employer-sponsored cancer coverage.

Meanwhile, IBM's N780RW flew from Danbury Municipal Airport to London Stansted in exactly 6.0 hours, a transatlantic dash that likely carried executives to the company's annual Think conference, which opened Tuesday in London.

And Neymar's PR-SMK, a Dassault Falcon 7X, departed from an undisclosed location and landed at Timberlachen Seaplane Base in Florida — a 4.7-hour flight that suggests the Brazilian footballer is either scouting property in the Sunshine State or making a discreet visit ahead of the upcoming MLS season.

Today's airspace is already tightening. The U.S. military reimposed its blockade on Iranian ports early Wednesday, per AP News, after Tehran's attacks on ships in the Strait of Hormuz escalated. The move effectively closes Iranian airspace to most civilian overflights, which will reroute Gulfstreams and Globals on the Dubai-London corridor. Separately, the Fontainebleau forest fire — started by a volunteer firefighter who confessed on July 14, per the Straits Times — continues to burn near Paris, with 1,900 hectares scorched and the A6 highway closed. That means any private jet heading to Le Bourget or Toussus-le-Noble today should expect delays and possible diversions. One tracked owner to watch: Elon Musk, who has a SpaceX launch window this evening from Cape Canaveral; his Gulfstreams are already pre-flighting at Van Nuys.

MGM Resorts' N781MM is currently airborne, having departed Sanford Seaplane Base at 08:12 local and heading west — likely returning to Harry Reid International in Las Vegas after a 4.1-hour round trip yesterday.

The desk expects at least one more Caesars or Wynn movement before sundown, as the summer convention calendar heats up.
