The event showcased helicopters used in the metro Atlanta area by law enforcement, emergency medical services and the military.
Jan Galt Russell, director of operations for the museum, said storms at the beginning of May caused the event to be postponed.
She added the timing was better this weekend with fewer competing events and school out for summer.
“I think people are looking for things to do with kids to keep them busy,” Russell said.
Russell anticipated a much higher turnout than last year’s 600 participants, which was the event’s inaugural year.
“We didn’t want anything too huge on the first go-round,” Russell said.
Jennifer Schestopol, a Cobb County school teacher who lives in Smyrna, said it was her family’s first time attending Helicopter Day, but that they had previously come to the Aviation Wing for an airshow.
Schestopol’s family were some of the first people to strap in for the day’s biggest attraction.
Blue Ridge Helicopters sold 5-minute rides to Kennesaw Mountain for $40 per person.
Riders were unloaded and loaded in less than a minute out of a black Robinson helicopter that can carry three passengers, plus the pilot.
Maggie Schestopol, 7, shouted, “That was awesome!” after landing.
Organizers expected to have 90 to 100 riders Saturday, with 50 people signing up in the first hour.
Last year, Blue Ridge Helicopters donated $5 from each ticket to the Marietta Museum of History to help maintain the Aviation Wing.
Schestopol said she might bring her fifth-grade class back to the park, especially because many of them are from low-income families and have already expressed an interest in joining the armed services.
The Aviation Wing is open Thursday to Saturday from 10 a.m. to 3 p.m. and offers group tours.
Planes are on permanent display from the U.S. Army and Airforce, and include a Mohawk from 1962 and a Lockheed JetStar that was once owned by Union Carbide Corp. and Kenny Rogers.
The JetStar was the first line of business planes, built in the 1960s and ’70s.
Cargo hatches and cockpit doors were open for participants to walk inside, and kids lined up to sit behind the controls.
Pilots and crew members were on hand to talk about the types of missions they complete and how the aircraft is controlled.
Oscar Johnson, 83, who lives in Kennesaw, asked Saturday morning if the organizers of the event would like him to share some expertise.
Johnson said he began his service history in 1948 when he enlisted in the U.S. Army.
He was a jump master for nine years.
During the Korean War, Johnson said he helped to drop CIA operatives behind enemy lines.
Johnson said he then went on to helicopter school and piloted 3,500 hours during the Vietnam War.
His military career ended after two years of flying Vice President Hubert Humphrey to his Minnesota home on weekends, Johnson said.
