Thunderbirds Jet Rehearsals Shatter Windows in Chicago High-Rises
Chicago residents reported shattered windows at multiple condominium buildings Friday morning following low-altitude rehearsals by the U.S. Air Force Thunderbirds demonstration team in readiness for this weekend’s Chicago Air and Water Show. The incidents, occurring along the lakefront, prompted 311 calls and raised questions about the impact of high-speed flight maneuvers near densely populated areas.
Initial Reports and Damage Assessment
The first reports surfaced around 10:20 a.m. from the 3100 block of North DuSable Lake Shore Drive in East Lakeview, where four lobby windows of a residential building were found shattered. A similar incident was reported approximately one mile north, near Lake Shore Drive and Irving Park Road, with windows broken both in the morning and again mid-afternoon. Damage across both locations is estimated to be in the tens of thousands of dollars.
Residents described a sudden, powerful shockwave coinciding with the Thunderbirds’ flyover.James Baran, a board member at 3180 north DuSable Lake Shore drive, recounted, You felt it. I actually felt it in my body.
He described glass flexing near his face, just a foot away from impact. Steven Cosgrove, another resident, stated, Instantly afterward, I heard a colossal kaboom.
While upper-floor windows are constructed with safety glass, the lobby windows in both buildings were made of standard plate glass, proving more vulnerable to the pressure wave.
Did You Know?
The pressure wave created by aircraft exceeding the speed of sound can cause significant damage to structures, even without direct impact.
Air Force Response and Inquiry
The United states Air Force Air Demonstration Squadron issued a statement asserting that the Thunderbirds did not exceed the speed of sound during the practice demonstration. The statement read, A thorough review of the practice determined the Thunderbird jets did not go supersonic at any point during the demonstration.
Though, residents remain skeptical, with some suggesting the pilots may have briefly “goosed the throttle” causing a localized sonic effect.

The Chicago Air and Water Show
The incidents occurred during preparations for the annual Chicago Air and Water Show, scheduled for this weekend. The show, a beloved city tradition, features performances by the U.S.Air Force Thunderbirds and the U.S. Army Golden Knights, attracting large crowds to North Avenue Beach and Lincoln park. The show’s popularity highlights the public’s fascination with aerial demonstrations, but also raises concerns about safety and potential disruptions to daily life.

The Federal Aviation Administration (FAA) confirmed it was not involved in the investigation of the broken windows. City officials have yet to release a statement regarding the incidents, and the Department of Cultural Affairs and Special Events did not respond to requests for comment.

Understanding Sonic Booms and Aircraft Pressure Waves
The phenomenon of windows shattering due to aircraft noise is linked to the creation of pressure waves, especially those generated when an aircraft approaches or exceeds the speed of sound.A sonic boom is the audible manifestation of this pressure wave. Even subsonic flight can create significant pressure fluctuations, especially during rapid maneuvers. According to a study by the National Research Council,Sonic Boom research in the United States,understanding and mitigating the effects of sonic booms is crucial for enabling future supersonic flight technologies.
