Overview

• Thousands of spectators lined Chicago’s lakefront Saturday to watch the U.S. Air Force Thunderbirds and U.S. Army Golden Knights headlining performances.
• Rehearsals on Aug. 15 included high-speed flyovers that shattered windows at multiple Lakeview-area buildings, notably boarding up the lobby of 3180 N. Lake Shore Drive.
• Doormen and residents described a sonic-boom-like blast and unusually low passes that shook structures while the FAA reported no unusual flight activity during the practice.
• Chicago police filed reports and building managers ordered emergency board-up services as show organizers vowed to review the incident.
• The two-day show continues Sunday under established safety zones and temporary flight restrictions with organizers monitoring further FAA findings on the cause of the Friday damage.
