The flight John Gervase was on was the very first Chicago Honor Flight to include veterans from the Korean War era, said Mary Pettinato, co-founder and CEO of the nonprofit organization, which began in 2008 as a provider of no-cost trips to Washington D.C. for World War II veterans. As fewer World War II veterans are signing up to take part in flights, trips are now opening up to military veterans of the next war era, she said.
