(LONDON) -- Two U.S. balloonists taking part in the 54th Gordon Bennett Gas Balloon Race are missing over the Adriatic Sea. According to Maresciallo Maccheroni of the Italian Coast Guard, the Coast Guard of Bari received a call from the Americans Wednesday morning saying they were having difficulties. The line then dropped, and they did not hear back from them. Five aircrafts and three boats are searching for the balloon about 13 miles north of Cap Guardino, in the location the balloonists mentioned. The weather could potentially hamper rescue effots, as winds travel between 16 and 18 knots.
