Two airmen from Eglin Air Force Base in Florida were sent to the hospital but were released without injuries after an indirect lightning strike on the flightline Wednesday night.

The 53rd Wing said in an email that the airmen were assigned to the 34th Fighter Squadron from Hill Air Force Base in Utah, and they were in the process of clearing the flightline when a nearby indirect lightning strike occurred about 8:20 p.m. One airman was closing an F-35 canopy, and the other was winding up a grounding wire, 53rd spokeswoman Maj. Ashley Conner said.

The airmen were taken to the emergency room at Eglin for observation, Conner said. No aircraft or equipment were damaged.

Conner said that flightlines are cleared when lightning is observed or lightning warnings are issued.
