In April, the Boeing Test & Evaluation team brought the 747-8 Freighter to a long runway in California to simulate the ultimate rejected takeoff (RTO). Crews loaded the airplane above its maximum takeoff weight of 975,000 pounds (443,181 kilograms) and installed a set of 100% worn-out brakes.
After the airplane comes to a stop, it's estimated to be more than 2,500 degrees Fahrenheit (1,400 degrees Celsius) inside the brakes.
