On July 29, the President intended to share his schedule with his Twitter followers, announcing that he was aboard Air Force One. Trump tagged the plane’s official Twitter account in his post.
Or he thought he did. The plane’s account is @AirForce1. Trump entered the handle @AirForceOne_HQ. That is the Twitter account for a commercial HVAC contractor in Ohio. Trump was far from the first person to ever make the mistake, but he was definitely the one with the highest profile.
