Eleven survivors of a plane crash off the Florida coast endured five harrowing hours adrift on a life raft, with no means of communication and an approaching thunderstorm.

Huddled under a tarp for meager protection, their desperate wait ended when U.S. military search and rescue crews appeared overhead, rescuers recounted during a news conference on Wednesday.

Air Force Capt. Rory Whipple, a combat rescue specialist who jumped into the water to reach them, described their ordeal.

“You could tell just by looking at them that they were in distress — physically, mentally and emotionally,” he said. “You have to imagine the emotional injuries that they sustained out there, not knowing if someone was going to rescue them.”

The plane, a Beechcraft 300 King Air turboprop, was on its way from Marsh Harbour, on the Bahamian island of Great Abaco, to Grand Bahama International Airport in Freeport when it suffered engine failure Tuesday, authorities said. The pilot ditched the plane in the water about 50 miles (80 km) off Vero Beach, Florida, and managed to get its 10 passengers, three with minor injuries, onto a yellow life raft.

Air Force Reserve Maj. Elizabeth Piowaty credited those efforts, saying the pilot would have been concerned about ocean swells and slowing the plane as much as safely possible before impact.

“I’ve not known anyone to survive a ditching in the ocean,” said Piowaty, who commanded a HC-130J Combat King II plane that assisted with the rescue. “From what I’ve seen, for all those people to survive is pretty miraculous.”

The downed plane’s emergency beacon alerted the U.S. Coast Guard to its location. At the time, the Air Force Reserve’s 920th Rescue Wing had a crew already airborne conducting a training mission in a HH-60W Jolly Green II helicopter. The crew was redirected to help with the search.

Piowaty said that after locating the survivors, her aircraft passed overhead and dropped a survival kit that included two additional rafts, food and water. The survivors were then able to spread out, and the crew of the HH-60W, including Whipple, was able to hoist them to safety amid 3- to 5-foot (1- to 1.5-m) swells, raising the last survivor just a few minutes before the helicopter would have been forced to refuel.

There was no sign of the downed aircraft, Piowaty said.

All 11 survivors were flown to awaiting emergency medical services at Melbourne Orlando International Airport, authorities said. All were reported to be in stable condition.

The U.S. Federal Aviation Administration said it would investigate the crash.
