NASA's Ames Research Center said its fire department planned aircraft firefighting training at Moffett Federal Airfield in California's Silicon Valley from Tuesday, Sept. 8, through Friday, Sept. 11, 2026, according to a media advisory published Sept. 4, 2026. The sessions were planned for 8 a.m. to 8 p.m. PDT.

The training was to use a propane-fueled aircraft fire simulator. Because the simulator runs on propane, NASA said very little smoke should be produced during the controlled training fires, though flames might be visible to drivers on U.S. Highway 101.

NASA said the training was intended to prepare the center's first responders for a variety of realistic aircraft firefighting scenarios.
