Firefighters at Ellison Onizuka Airport are running live-fire training today, which is routine but could look alarming to nearby residents.

• Aircraft rescue firefighting crews are holding live-fire drills at the airport from 7am to 2pm.
• People in the area may see extra emergency vehicles and smoke during that window.
• Separately, excavation work caused a collapse nearby, and officials are still investigating the cause.

Outlook: Activity around the airport should return to normal after the training wraps up at 2pm.
