The rumble moving out across the sky on Wednesday will not be the sound of an oncoming storm, but rather an expression of gratitude for the state's healthcare workers and others.

Four F-15C Eagle Tactical Fighter Jets, with the 144th Fighter Wing of Cal Guard out of Fresno, will be performing a formation flyover throughout California in a salute to healthcare workers, first responders, and everyone on the frontlines in the fight against COVID-19. The flyover will start at 10 a.m. Wednesday and is scheduled to takeoff from California Air National Guard Base, Fresno. The jets will pass over medical facilities in the San Joaquin Valley, Sacramento Area, Bay Area and Southern California, covering the towns of Reedley, Selma, Madera, Sacramento, Richmond/Oakland, San Jose, Monterey, Los Angeles and Clovis before returning to base in Fresno.

The schedule has the jets flying over Merced at 10:16 a.m., so Turlock residents should be looking upward around that time.

The four jets are part of the nation-wide salute by the Air Force for health care workers and those on the front line. The pilots plan to do a low pass at several locations including the Capitol, California Office of Emergency Services, California Highway Patrol and Cal Fire headquarters locations.

Residents in these areas will be able to see the flyover from the safety of their homes and should maintain all social distancing guidelines during this event. They should also refrain from traveling to landmarks, hospitals and gathering in large groups to view the flyover. They can also expect to hear jet noise as the aircraft fly overhead.

Cal Guard is encouraging viewers to tag them on social media in photos and videos of the formation with the hashtags #144FW, #AmericaStrong, and #CaliforniaNationalGuard.

All times are subject to change based on weather and environmental considerations.
