Cold start
EGLIN AIR FORCE BASE, Fla. – Airman 1st Class Cody Snodgrass, 46th Aircraft Maintenance Squadron, waits for an F-16’s engine to fire up before it taxis to the runway. Northwest Florida was hit by a massive cold front sending temperatures plummeting below freezing. Despite the cold, the maintainers must prepare the jets and get them in the air.
