(CBS) — Thousands of people at Chicago’a lakefront went home disappointed as low cloud levels prevented airplane acts from performing at the Air and Water Show Sunday.

The show was supposed to start at 10 a.m. but was delayed until 1:30 p.m. when a Chicago Fire Department rescue crew and then a Chicago Police helicopter performed. Before that, Jim Cornelison sang the national anthem and then took part in the “Ice Bucket Challenge.”

After the rescue crews performed the show was again suspended, this time for good. A fog ceiling that hovered around 4,000 feet at Gary’s airport was preventing planes from being able to take off.

“We slid the show as far as we could throughout the day and you just get to the point where we ran out of waivered air space time to be able to fly,” John Trick, Chicago Air Show Manager

Tom Kokinakos came in from Racine, Wisconsin.

“You can still see the fog and half the buildings downtown are covered. I get it, but hopefully we will try again next year,” said Kokinakos.

Since 1973, only between two percent and three percent of August days have had clouds below 1,000 feet according to the Chicago National Weather Service.
