Air Combat USA, established in 1988, is the original civilian dogfighting school. With over 18 years of experience and over 38,000 guest pilots flown, Air Combat USA is the largest, most recognized air combat school in the world. We've been featured on hundreds of television shows including The Apprentice and Good Morning America! As the industry leader, we work hand-in hand with the Federal Aviation Administration (FAA) and other governing agencies to define the parameters and establish safety guidelines used to regulate the air combat industry.
The mission at Air Combat USA is to provide an extraordinary fighter pilot experience! We set the standard for program design and execution, offering a fighter pilot experience second to none! Captain Mike Blackstone, founder and president of Air Combat USA, developed and patented the tracking system that verifies an air-to-air "kill" and equipped the aircraft with onboard cameras to ensure that the entire experience is recorded on digital videocassette for playback after the engagements. He is determined to ensure that "everything is real…except the bullets!"
