Allison Churchill and Robert Johnson outlined some of the more fascinating details about the President of the United States’ personal jet:

• The hangar in which Air Force One is kept has a firing range so that people can practice their shooting.
• For journalists to be cleared to go on the plane, they must go through ten security screens by agencies such as the Secret Service and the Air Force.
• Along the top of the plane there is an ‘attic’ filled with radio jammers, antennas, and sensors that detect attacks.
• On the day of 9/11 the President was taken into the air on Air Force One because it was deemed to be the safest location for him. It was the only aircraft above North America that day and three F-16s escorted it as it flew close to the speed of sound.
