Charles Dale, Frank Lape, Elston Peters and Dwayne Driscoll went on the most recent Honor Flight out of Waterloo.
They all live at Bridges Senior Lifestyle Living in Waterloo, and they all served during the Korean War.
Dale and Peters were in the Army. Driscoll was in the Navy on the aircraft carrier Midway, and Lape served in the Air Force.
"Probably one of the best experiences I had was bringing the 28th Bomb Squadron home from Okinawa," said Lape. "I met all the crew."
The four friends spent June 18 visiting the monuments and memorials in Washington, D.C., as part of Honor Flight.
"I think it was beautiful," Dale said. "I really liked it."
"It was all good, but changing of the guards (at Arlington National Cemetery) is what I thought was best," said Peters.
In May, Peters was awarded five services medals he earned during the Korean War but never received.
All the men said a highlight of the trip to D.C. was seeing the Vietnam and Korean War Memorial Walls.
"It was nice. Words can't describe it," said Lape.
It did rain on the trip and the men didn't see much of each other throughout the day, but they were able to swap stories and photos once they returned.
All the men were surprised at the reception they got when they arrived back at the Waterloo Regional Airport Tuesday night.
"It was real nice when we got back to the airport," Driscoll said. "I think we all couldn't believe the number of people there to greet us."
"I live in a great community," added Lape.
The men thanked those who organize the Honor Flights and everyone who donated to make these trips possible for veterans.
Darol Burge also lives at Bridges and went on this past Honor Flight.
Another veteran was supposed to go on the flight, but Howard Masters died at the beginning of May just several weeks before having the opportunity to make the trip with his friends.
