Some World War II veterans got a special preview of this weekend's big event. They braved the heat to enjoy the show.
It runs on Saturday and Sunday from 11 a.m. until 4 p.m. This year's show will include actor Vince Vaughn, who will perform a tandem jump with the U.S. Army Parachute Team Golden Knights, and is expected to land on North Avenue Beach at around 11 Saturday morning.
The biggest draw will undoubtedly be late in the afternoon of each day when the Navy's Blue Angels perform.
Hot weather is expected to add an extra punch to this weekend's massive crowds. It is very, very hot, but that is not discouraging people from coming out.
While folks are taking advantage of the largest pool (Lake Michigan), emergency officials are concerned about everyone else.
"High temperatures can pose serious harm to your personal health and can be hazardous for the elderly, children, and pets," said Jose Santiago, OEMC director.
Saturday morning also marks the 81st edition of the Bud Billiken Parade. The nation's oldest African-American parade steps off at 10 a.m. on King Drive on the city's South Side.
The heat is prompting parade organizers to offer relief. There will cooling buses at every underpass between Lake Street and Fullerton.
The heat is hardly an issue for a group of World War II veterans taking part in a fundraiser for the Honor Flight charity organization. For many, seeing the vintage planes brings back amazing memories.
"It is a thrill to be here and meeting the vets and the old guys. And hell, I'm only 92," said Norval Nelson, World War II veteran.
