IBM's Gulfstream G650ER returns to Westchester the week of a historic chip breakthrough

IBM's Gulfstream G650ER, tail N780RW, was tracked flying from Swan Creek Airport in Delaware to Westchester County Airport on June 30, 2026, a 45-minute hop at 23,000 feet.

If IBM leadership was aboard, the arrival at Armonk headquarters comes the same week IBM announced the world's first sub-1 nanometer chip technology, a breakthrough the company says could extend Moore's Law another decade [newsroom.ibm.com](https://newsroom.ibm.com/2026-06-25-ibm-debuts-worlds-first-sub-1-nanometer-chip-technology). The new 'nanostack' architecture packs nearly 100 billion transistors onto a fingernail-sized chip, promising up to 50% more performance or 70% greater energy efficiency than IBM's 2 nm node chips. The timing would suggest a return to home base following the announcement and any related internal briefings.

The aircraft, one of two G650ERs in IBM's fleet, is leased through Banc of America Leasing. Recent flight patterns show the jet moving frequently between Armonk, the D.C. area, and regional airports, consistent with executive travel for meetings and corporate events. IBM's security policy requires all air travel by the Chairman and CEO to be on company aircraft.
