Two small planes have collided over the Everglades, crashing into the swamp, and authorities said there were no survivors. A Piper aircraft and another unknown aircraft crashed at about 3 pm (local time) on Sunday, Federal Aviation Administration spokeswoman Kathleen Bergen said.
Authorities believe there was only one person on board the Piper, but they had no information yet on the second plane, Bergen said.
The area where the planes went down is only accessible by airboat, and the wreckage quickly sunk, said Palm Beach County Fire-Rescue Captain Don DeLucia.
There were no survivors, DeLucia said, although no bodies had yet been recovered. "They're in the water, under the water," DeLucia said.
"We have no idea how many victims there are. It could be as few as two, or more." He said the recovery effort would continue until dark, then resume at daybreak. The planes collided about 23 kilometres northwest of Pompano Beach in southeast Florida.
