Keith and his team presented their work showing that future aircraft should carry eight machine guns capable of firing at least 1,000 rounds per minute.

This was for data on future rocket-powered aircraft.

The calculation, known as the area rule, was reflected in the design of many future aircraft.

American officials believe that Beijing is buying the planes in hope of acquiring production technology so that future aircraft can be assembled at home.

Stout gave speeches across the country touting that all future aircraft would be metal.

"You're opening the door to future aircraft," he said.
