The Air Force admits a public 'oopsie' about once every 3-4 years. Typically they're small items that land fairly close to base proper, like a small drone that landed on someone's roof with no ill effect, but a couple years back, they did drop a plane on someone's house in Valparaiso when the pilot had an emergency just short of the north-south runway.
Also, there's a ton of buried munitions in the area because the Panhandle has been used for military training essentially since the Spanish first made landfall. Most of it is inert. But if you do find something that looks like a bomb, Civil War cannonball, etc. Please leave it in the exact spot you find it, move a safe distance away, and call 911 and let the nice fellows at the Navy bomb squad handle it on site. Do NOT put it in the back of your pickup and drive it to the fire station. (Which seems to be the normal plan of action in these parts when someone finds something)
