An airplane carrying Secretary of War Pete Hegseth was forced to make an emergency landing in the UK Wednesday due to a crack in its windshield, officials said.

Pentagon spokesperson Sean Parnell wrote on social media that on the way back to the U.S. after NATO’s Defense Minister meeting in Belgium, the plane made an “unscheduled landing in the United Kingdom” because of a crack in the aircraft’s windshield.

The plane landed based on standard procedures, and all of the passengers on board, including Hegseth, were safe, Parnell added.

“All good. Thank God,” Hegseth wrote on X. “Continue mission!”

Hegseth was traveling in a C-32A, a modified Boeing 757 used by the Air Force for VIP transport. Other top leaders, including Secretary of State Marco Rubio, Vice President JD Vance and occasionally, even President Donald Trump, use the aircraft when visiting airports with runways too short for the modified Boeing-747 Trump typically uses as Air Force One.

It was unclear what caused the crack in the plane’s windshield.

Flight tracking data showed that the plane took off from Brussels and made it past Ireland before turning around to land at Royal Air Force Mildenhall in England at 7:07 p.m. local time. It was not known what time the plane initially took off.

Hegseth and previous Secretaries of Defence have traditionally used a different aircraft for foreign travel, the Boeing E-4B.

The Boeing E-4B is a modified Boeing-747 that has been hardened for use as an airborne command post by the president or Pentagon leadership during nuclear conflicts. It is known within the Air Force as “Air Force One when it counts” and the “Doomsday plane.”

It was not immediately clear why Hegseth was traveling on the smaller, C-32 plane.

The C-32, which had to perform an emergency landing, has less capabilities than the E-4B, but is decked out with a more luxurious interior thanks to upgrades made during Trump’s first term as president.

During his time in Brussels, Hegseth warned the U.S. would “impose costs on Russia for its continued aggression” if the war in Ukraine does not come to an end.

“If we must take this step, the U.S. War Department stands ready to do our part in ways that only the United States can do,” Hegseth said at a meeting of the Ukraine Defence Contact Group of Kyiv’s allies at NATO headquarters.

Hegseth did not elaborate. His comments came as Trump’s administration is considering a request by Ukraine for long-range Tomahawk missiles.

Earlier this year, an Air Force plane carrying Rubio to Munich was forced to return to Washington after experiencing a mechanical problem.
