Defense Secretary Pete Hegseth’s aircraft made an emergency landing in the United Kingdom on Wednesday due to a crack in the aircraft’s windshield, a Pentagon spokesperson said.

Hegseth’s plane incurred the crack as he was returning to the U.S. from the NATO Defense Minister’s meeting in Brussels. Hegseth and the rest of the plane’s passengers were unharmed.

“On the way back to the United States from NATO’s Defense Ministers meeting, Secretary of War Hegseth’s plane made an unscheduled landing in the United Kingdom due to a crack in the aircraft windshield,” Pentagon spokesperson Sean Parnell said in a social media post. “The plane landed based on standard procedures and everyone onboard, including Secretary Hegseth, is safe.”

Hegseth confirmed he is “all good” after the emergency landing in a post on X.

The unscheduled stop caps a consequential trip to Brussels for Hegseth, who warned the U.S. will “impose costs on Russia” if it does not take steps to end its war with Ukraine. The comments signal a growing frustration with Russia from the Trump administration, which has ramped up its pressure on Putin in recent months.
