As search crews continued to comb the Adriatic Sea on Sunday for two missing American balloonists, including a Denver radiologist, details were revealed about what was said in the team's final radio transmission. Richard Abruzzo, 47, of Albuquerque and Carol Rymer Davis, 65, of Denver were flying in the 54th Gordon Bennett Gas Balloon Race when contact was lost Wednesday morning. Since then, search and rescue teams with the Italian coast guard, the U.S. Navy and Croatian coastal aircraft crews have been scouring the area. In an update with reporters over the weekend, Abruzzo's wife said rescuers were reviewing transmissions they received from the balloon's transponder. Nancy Abruzzo read part of her husband's last transmission verbatim: "I am in a thunderstorm. The situation is not easy. We are headed for coast but not in danger," Richard Abruzzo said. Minutes later in the transmission Nancy said it read: "Descending upon, descended, descending rapidly upon the sea." The balloon, which took of from the United Kingdom, was over the Adriatic Sea at this point when all contact was lost. The race organizer said the balloon was equipped with survival suits, life jackets and two single-person life rafts.
