Crews are due to resume the search for a man who reportedly fell into the sea from a small plane off Florida.
The call for help came on Thursday afternoon, when the pilot of a Piper PA 46 aircraft radioed "mayday, mayday, mayday," and told an air traffic controller that a door was ajar and a passenger had fallen from the plane.
Crews from US Coast Guard, Miami-Dade Police and Miami-Dade Fire Rescue searched into the evening.
Police spokesman Javier Baez says they have no evidence of foul play, and are gathering as much evidence as possible.
Both the Coast Guard and fire rescue officials say they had not determined if the call was legitimate.
