Boeing 747-8 performs ultimate rejected takeoff

It’s one of the most dramatic tests for a new airplane as the pilot slams on the brakes while going 200 miles per hour (320 km/hr). Watch as the 747-8 Freighter, loaded to maximum takeoff weight and equipped with 100% worn out brakes, perform a rejected takeoff without thrust reversers.
