In 1933 the government got the first plane for presidential travel, however, it was only until 1959 that the planes became known as Air Force One.
The Air Force One's design was made by legendary designer Raymond Loewy.
The flying Oval Office nowadays features "4,000 square feet of interior space incorporating presidential living quarters, work areas, meeting rooms, and 2 galleys capable of serving 100 people at a time."
Conducted at Stanford University, a graduate student made 3D-printed goggles for a bird to fly through laser light in order to study the bird's flight physics.
"Using a high-speed camera, scientists captured the swirling vortices produced by a slowly flying bird. Surprisingly, they found that the vortices rapidly dissipated. The unexpected effect suggests that scientists need to rethink methods for calculating the lift produced under such conditions"
