But the Secret Service and other security officials did not consider that the hasty upgrades it received had given it the level of security of the older Air Force 1s. Therefore, they first made the switch to an older Air Force 1, and sent the Qatar plane on to Britain, before the switch to the military jet. Trump said that he had sent the Qatar plane to Britain because US military personnel at the base wanted to see the plane. The accusations of the leaks only confirmed the security issues with the Qatar plane that Trump and officials had denied. The old Air Force 1s and the Qatar-donated plane that is to serve as another Air Force 1 are all variations of Boeing 747s.
