BRISTOL, England (KUSA) - Carol Rymer Davis was taking part in the Gordon Bennett Cup race with her co-pilot Richard Abruzzo. Race officials lost contact with the pair's hydrogen balloon at 8 a.m. local time. Officials say there were thunderstorms in the area.
According to the Gordon Bennett Control Centre, Davis and Abruzzo's balloon is equipped with a satellite telephone, VHF radios, radar transponder and two mobile telephones. They say they have been unable to make contact with the balloonists.
The control center says they have not received a signal from the Emergency Location Transmitter on the balloon, which should activate if the device has contact with water. The balloon also has survival suits, lifejackets and two single-person life rafts.
Rescue crews say they have been unable to locate the signal from their transmitter.
The search continues Thursday.
