United 787 flight to Munich diverts to Boston after cockpit windshield cracks

A United Airlines Boeing 787-8 flying from Washington Dulles Airport (IAD) to Munich (MUC) diverted to Boston Logan Airport (BOS) on August 10, 2026, after the crew reported a cracked cockpit windshield less than two hours into the transatlantic flight.

United Flight 108 departed IAD at about 17:15 local time with 175 passengers aboard. The aircraft had turned northeast toward the Atlantic before reversing course over southern Maine and heading for BOS.

The 787 landed safely in Boston just before 19:30. Massport Fire and Rescue responded after the aircraft arrived. No injuries were reported.

United said the diversion was made to address damage to the outer layer of the aircraft’s multilayer windshield.

Aircraft windshields are made up of multiple layers designed so the windshield can continue to function if one layer is damaged. United said the aircraft remained safe to operate during the diversion.

The cause of the cracks has not been determined.

The FAA said the crew reported a cracked windshield before landing and that the agency is investigating the incident.

The flight was canceled after arriving in Boston. United arranged alternate transportation for the passengers and provided hotel accommodations, meal vouchers and compensation.

The aircraft involved remained on the ground in Boston after the incident, according to flight-tracking information.

A similar incident involved a KLM Boeing 787-9 in February 2025, when the aircraft landed safely in Costa Rica after the captain’s front windshield cracked during descent.

In July 2025, a United 787 operating the same Washington-to-Munich flight returned to IAD after the crew reported a left engine failure shortly after takeoff. That aircraft landed safely after dumping fuel.The post United 787 flight to Munich diverts to Boston after cockpit windshield cracks appeared first on AeroTime.
