The US Coast Guard on Tuesday spent a fifth day searching for two missing 14-year-olds off the Florida Coast.
Perry Cohen and Austin Stephanos have not been seen since they went boating over the weekend.
The search for the boys is being conducted by land, sea and air.
Lieutenant Janelle Setta of the US Coast Guard piloted a C-130 aircraft that took part in the search on Tuesday.
Setta said that the search had uncovered "multiple" items in the water, but said could not speculate as to whether these belonged to the boys or their boat.
