81 flights, 758 tonnes of CO₂, and a Poonawalla transatlantic marathon

758.3 tonnes of CO₂. That’s the single most striking number from yesterday’s ledger — the combined carbon footprint of 81 private flights that logged 77,984 miles and 179.8 hours airborne. The top mover was Sheikh Mohammed bin Rashid Al Maktoum, whose two legs (7.2h Dubai→Stansted, then 6.9h Stansted→JFK) accounted for 108.7 tonnes alone. The destination heat-spot was OEDF, which drew two arrivals — a rare clustering for the Saudi airfield.

The longest flight of the day belonged to the Poonawalla family. Their Gulfstream G650ER VT-CDC departed Chhatrapati Shivaji Maharaj International Airport at 02:14 UTC and touched down at London Luton 9.9 hours later — a transcontinental arc that put the Serum Institute’s leadership in the UK by breakfast. The timing aligns with ongoing vaccine-distribution talks between the Serum Institute and the British government, though neither side has confirmed a meeting. The flight alone emitted roughly 45 tonnes of CO₂.

Elon Musk’s G450 N450GG flew from Draughon Miller Central Texas Regional to Shannon in 8.4 hours — a quiet repositioning that deposits him on the western edge of Europe the same week xAI absorbed its second legal loss to OpenAI [coingape.com]. Meanwhile, Sheikh Mohammed bin Rashid Al Maktoum’s A6-MMM completed a rare double: Dubai to Stansted, then onward to JFK, a 14.1-hour day that made him yesterday’s top CO₂ emitter.

The Nike Gulfstream G650 N6453 also crossed the Atlantic, Luton to Boeing Field in 8.6 hours, likely ferrying executives ahead of a product-review cycle in Beaverton.

As of this morning, Elon Musk’s Gulfstream G800 N8628 is showing a filed flight plan from Shannon to Hawthorne, per Celebplanes live tracking [celebplanes.com]. That return leg would close a three-jet day for Musk — his G450 arrived yesterday, and his G650ER N628TS remains at Starbase. The timing puts him back in California by early afternoon, just as the Justice Department’s brief defending xAI’s Mississippi data center lands in federal court [ibtimes.sg]. Also worth watching: Sheikh Mohammed bin Rashid’s A6-MMM is parked at JFK; a departure toward Dubai or a Gulf stop would push his two-day total past 20 hours.

The Poonawalla family’s VT-CDC is still on the ground at Luton. If it wheels east this evening, it will be the second 10-hour leg in 48 hours — and a test of the desk’s prediction model, which went 24-for-55 yesterday. One to score by sundown.
