A veteran is greeted by military members currently serving as he steps off a bus to board a plane May 3, 2015, at Denver International Airport in Denver. The veteran, along with 75 other World War II, Vietnam and Korea veterans, along with terminally ill and Purple Heart recipient veterans, took a trip to Washington D.C. to visit military memorials. The overnight trip was hosted by the Honor Flight of Northern Colorado and is offered every year free of charge for the vets through donations from the public.
