Two hundred and fifty vets who served in the Pacific theater left from O'Hare airport Wednesday. They are taking several 'honor flights' to visit the World War II Memorial in Washington DC.
The organization provides free flights for the vets. The men exchanged stories and were treated to a show.
Some of the vets say they are overwhelmed.
"Just unbelievable. The military, as the bus pulled up, they all saluted us," said Tom Oliva, World War II veteran.
"I think it's great and I look at these fellows and I think back 40, 50 years ago what did they look like or what did I look like?" said Bill Hay, World War II veteran.
The non-profit Honor Flight Network was founded by four women shortly after the World War II Memorial was dedicated in 2004.
