Trump's secret plane switch: How Air Force One protects the president from threats

President Trump's secret plane switch in Turkey highlighted Air Force One security protocols. A threat from Iran forced Trump to switch planes, using a catering truck to move to a smaller aircraft. He flew to Turkey on a Qatari-gifted plane, then returned on an older presidential plane due to security concerns. All three planes flew to the U.K. before Trump flew home on the Qatari plane.
