As of 8 a.m., large crowds of spectators had already packed the beach, more than two hours before the event's scheduled start time.
U.S. Air Force, Coast Guard, Marine and Navy aircraft pilots will showcase their moves including stunt performances and precision parachute drops. Vintage planes and even an experimental flying car will also be on hand.
A show-stopping finale is also expected from the world-famous Air Force Thunderbirds, celebrating the military branch's 75th anniversary. Six elite pilots will showcase the capabilities of the F-16 fighter jet.
"A roll is when the aircraft will slowly roll over, and we'll do that in formation, " said Major Bobby Gulla, a Thunderbirds maintenance officer. "And then you'll see a loop -- pull straight up into the air, come right down, make a beautiful circle.
"If the weather cooperates we'll draw a heart in the sky for everybody here today. And then you'll just see a lot of precision flying at it's best."
