This is the incredible moment three huge passenger planes staged a high-speed drag race at 35,000 feet in the air.

The video shows a Boeing 747 hurtling past another aircraft, a Boeing 737, as captured from a captain in a cockpit of a third plane, which was flying below.

To the untrained eye, the planes look like they are extremely close in proximity, but in fact they would have been around 2,000 feet apart.
