A Huey helicopter from the Aircraft Operations branch at NASA's Kennedy Space Center in Florida hovers over the Indian River Lagoon after a group of Emergency Response Team officers from the center's Protective Services branch dropped from the helicopter during a training exercise. The training session focused on safely entering the water, something the ERT could be required to perform in certain situations at the center. Photo credit: NASA/ Dan Casper
