The F-35 is the most powerful single-engine fighter in history, and has three variants. The AA-1 is the smallest and lightest of the models, and is designed for conventional takeoff and landing.

In 2014, a U.S. Navy F-18 jet flying over the Pacific Ocean about 35 miles southwest of San Diego went supersonic.

But those jets rarely break the sound barrier over land unless they face a real-world emergency, to prevent panic among unsuspecting residents on the ground and damage to the community around them.
