Overview

• The Air Force says avionics data and official documentation show no F‑16 exceeded Mach 1 during the Aug. 15 practice.
• An aeronautics professor who reviewed resident videos said the sounds were clearly sonic booms and likely shock waves from localized supersonic flow.
• Lake View residents reported two powerful blasts and lobby window damage at 3180, 3600 and 3950 N. DuSable Lake Shore Drive and 4200 N. Marine Drive.
• Ald. Bennett Lawson urged building managers to file claims with the city for the city‑sponsored event, as OEMC said it is looking into the incident.
• The FAA referred questions to the Air Force, and prior Blue Angels and Thunderbirds cases show similar shock‑related damage and compensation processes.
