If you live in downtown Miami, you've probably noticed something unusual in the sky the past few nights.
Residents have been posting videos on YouTube of unmarked military helicopters flying through Brickell at late night hours, creating lots of noise and a little concern.
The videos, titled "Miami Under Attack" and "POLICE STATE 2011: Homeland Security/ARMY Black Helicopters in Drill Over Downtown Miami," show the black choppers navigating through the high rises, hovering in place and flying pretty low.
But Military officials released a statement Wednesday saying the helicopters are part of a military training exercise focusing on operating in urban environments, but didn't give any specific details.
the training exercises, conducted with the support of the Miami Police Department, were being done at night to minimize the impact on Magic City citizens, the statement said.
"We recognize this training has an impact on Miami residents and we appreciate your support during this critical training event," the statement reads.
Wednesday was expected to be the last night of the training.
