(BBC) Rescuers searching for the adventurer Steve Fossett in the Nevada desert have found old wrecks of planes, some of them from crashes decades ago. Forty-five aircraft are involved in the search for the missing millionaire who disappeared on Monday while flying alone in his small plane.
Rescuers have scoured an area of 10,000 sq miles (25,900 sq km) of remote terrain, as yet unsuccessfully.
The planes are using thermal imaging so they can search day and night.
After six days of intensive searches, rescuers have not found any sign of Mr Fossett's plane, instead they spotted six planes which crashed in the desert in earlier years.
