WASHINGTON (AP) — On Tuesday evening, Air Force One, carrying President Donald Trump, made an unscheduled return to Joint Base Andrews roughly an hour after setting off for Switzerland.

Karoline Leavitt, the White House press secretary, explained that the crew detected “a minor electrical issue” shortly after takeoff. Exercising an abundance of caution, they opted to turn the plane around.

According to a journalist on board, the press cabin lights flickered off briefly post-departure, though no immediate clarification was provided. About 30 minutes into the journey, passengers were informed of the decision to return.

President Trump then switched to an Air Force C-32, a customized Boeing 757 typically used for domestic trips to smaller airports, and resumed his journey to the World Economic Forum in Davos, departing shortly past midnight.

The current aircraft serving as Air Force One have been operational for nearly 40 years. While Boeing is developing replacements, the initiative has faced multiple delays. These planes are extensively modified to equip the president with survival features for diverse emergencies, such as radiation protection and anti-missile defenses. They are also fitted with advanced communication systems, enabling the president to stay in touch with military command and make decisions from any global location.

Last year, the ruling family of Qatar gifted Trump a luxury Boeing 747-8 jumbo jet to be added into the Air Force One fleet, a move that faced great scrutiny. That plane is currently being retrofitted to meet security requirements.

Leavitt joked to reporters on Air Force One Tuesday night that a Qatari jet was sounding “much better” right now.

Last February, an Air Force plane carrying Secretary of State Marco Rubio to Germany had to return to Washington because of a mechanical issue. In October, a military plane carrying Defense Secretary Pete Hegseth had to make an emergency landing in United Kingdom due to a crack in the windshield.
