IBM's Gulfstream G650ER lands at Westchester County the week of its sub-1nm chip breakthrough

IBM's Gulfstream G650ER, tail number N780TW, was tracked departing Raleigh-Durham International Airport at 17:50 UTC on June 30, 2026, and arriving at Westchester County Airport 1 hour and 23 minutes later, according to ADS-B data. The aircraft reached a maximum altitude of 29,000 feet and a ground speed of 492.7 knots on the short hop back to the company's home base near Armonk, New York.

If IBM leadership was aboard, the timing would align with a landmark week for the company. On June 25, IBM debuted the world's first sub-1 nanometer chip technology, featuring a revolutionary "nanostack" 3D architecture, as announced in a press release on IBM's newsroom. The breakthrough, covered by Ars Technica and MIT Technology Review, promises up to 50% more performance or 70% greater energy efficiency than IBM's 2nm node chips, and was developed at the company's Albany research facility.

The Raleigh-Durham area is home to IBM's Research Triangle Park campus, a major hub for client engagements and research. The flight from RTP to Westchester County is a familiar route for IBM's fleet, which includes two Gulfstream G650ERs. This particular movement follows a pattern of shuttles between the two locations, consistent with the company's operational needs in the wake of a major technology announcement.
