IBM's Gulfstream G650ER returns to Westchester after Boston visit during cyber defense push

IBM's Gulfstream G650ER, tail number N780TW, was tracked departing Boston Logan International Airport at 1:07 AM UTC on June 25, 2026, and arriving at Westchester County Airport 46 minutes later, after a brief repositioning flight. The aircraft reached a maximum altitude of 16,000 feet and a top speed of 384 knots.

If IBM executives were aboard, the return to Armonk would follow a week of significant cybersecurity and AI announcements. On June 22, IBM announced it had joined the OpenAI Daybreak Cyber Partner Program, bringing frontier AI into enterprise security operations, per a press release on newsroom.ibm.com. Two days later, on June 24, IBM, Red Hat, and Palo Alto Networks expanded Project Lightwell to help organizations respond to software vulnerabilities, as reported by newsroom.ibm.com. The Boston area is a key hub for IBM's research and client engagements, making this quick trip consistent with the company's operational needs.

The flight is part of a busy travel pattern for IBM's fleet of two Gulfstream G650ERs. Recent flights show the aircraft shuttling between Westchester, Boston, Chicago, and Washington, D.C., including a Boston visit on June 24. The company's most restrictive security policy requires all air travel by the Chairman and CEO to be on company aircraft, per disclosed filings.
