The St. Patrick’s Day parade participants won’t be the only ones causing all the ruckus Wednesday on Massachusetts Street.

Al Stuber, a retired Navy pilot and an engineer, is scheduled to lead a squadron of aerobatic sport planes in a flyover at 12:59 p.m. Wednesday, just before the parade’s scheduled start time. The parade starts at South Park and heads north up Massachusetts Street, across the Kansas River and into North Lawrence.

The planes may be familiar to football fans — the group often skywrites “KU” above KU home games.
