Along with Maywald, veterans of the Vietnam War era will be honored.
Admission to the event is free.
Ceremonies will begin with a reception at the terminal building followed by a mini parade of classic military vehicles at 11:30 a.m.
Following the parade, T-34s, Stearmans and T-6s will fly in formations.
At 1 p.m., the A-10 Warthogs are to fly over, followed by the B-52.
The veterans’ tribute program will be between 12:30 and 1:30 p.m. with the Gilmer High School band and Air Force Jr. ROTC programs participating. The International ALERT Academy Big Sandy will also join in the flag ceremonies.
Maywald received the Air Force Cross, the second-highest decoration for that branch of the services, as a result of his actions flying out of Nakhon Phenom Air Base, Thailand, during the rescue of Major Jerry Dwyer from the jungles of Laos.
Maywald, Gilmer High class of 1959 and a U.S. Air Force Academy graduate in 1963, was a member of the 23rd Tactical Air Support Squadron, which flew missions out of Thailand in O-2s, the military version of Cessna 337, as a forward air controller, giving information to other pilots on where to send their fire.
Maywald went by the handle, Nail 48, and Dwyer Nail 55.
As part of the program at the Fly-in, the rescue of Dwyer will be recreated with a swarm of L-19s and O-2s.
The East Texas Classic Packard Club is another invited guest, and there will be plenty of food, parachute jumpers, ice cream and rides for Young Eagles.
