 July is going to be hotter than ever because you get up to $50 off any smartphone at Appalachian Wireless to your agreement required. Better service? Bigger savings? That's today's Appalachian Wireless, an East Kentucky network company. Sunday night, 11 minutes into the fireworks display in Inez in Martin County, one of the largest fireworks shells of the show exploded on the ground, injuring several firefighters. The lift charge didn't lift the shell out of the tube. The shell detonated inside the tube, which caused the barrel that it was in and the sand to explode with it. Although the spotter knew the shell never left the tube, all seven firefighters in the area knew something was wrong. I mean these things, they make a sound, a certain sound when they come out of the tube. It just didn't sound right. Within seconds, the 8-inch fireworks shell exploded, sending pieces of the 55 gallon drum and the sand it was packed in flying in every direction, causing injuries to nearby firefighters. They were probably 30 feet away, 50 feet away from the actual site, and they were the ones that took most of the most of the impact. For the thousands of people who gather to watch fireworks shows, it's just entertainment. But the firefighters lighting the fuses know that disaster can strike at any moment. It's man-made, they're hand-made, and if somebody forgets one little thing, it can cause everything to go go crazy. Two firefighters were transported to the hospital by ambulance and two more were taken in personal vehicles, but all were treated and released Sunday night.
