Miami residents up on the balconies overlooking downtown Miami have been making amateur videos and posting them on YouTube. Tuesday night one of these videos showed the military helicopters flying over 395, right by the Miami Herald Building.
The amateur footage, shot by Atlanta resident Josh Epperson, also captured the sound of blank rounds being fired. In town for work, Epperson admitted he had no idea what was happening when he filmed the footage. "I heard the machine gun fire and then I hit the deck," he said. "I didn't know what to expect, and it was one of the loudest things I'd ever heard."
Thursday nights training took place near the Stephen P. Clark Center in Miami and a nearby Metrorail station where troops could be seen rappelling from the military choppers onto the Metrorail station platform.
