A pilot and two passengers are missing after a hot air balloon caught fire in Virginia, USA on Friday.
Witnesses said they heard calls for help from the balloon basket after it appeared to hit a power line in Doswell.
Police have not yet found the balloon.
Speaking to local TV station WWBT, Carrie Hager-Bradley said she saw the balloon in flames: "They were just screaming for anybody to help them".
The Guardian reports that the balloon had been taking part in the Mid-Atlantic Balloon Festival.
Virginia state police said: "No wreckage has been found yet, and there are no confirmed injuries or fatalities."
In 2012, a hot air balloon was forced to crash land on a Bath city centre road after there wasn't enough wind for it to gain altitude.
The Bath Building Society balloon carried 16 people in a trip over the city for two and a half hours, but got into trouble when it couldn't gain enough height.
Richard Morris, 29, bought his girlfriend, Lisa Camper, 31, a ride on the balloon as a Christmas gift for £150.
She told the Telegraph: "The balloon goes wherever the wind takes it but there was hardly any breeze so we reached 4,000ft and stayed circling Bath for two-and-a-half hours.
"Towards the end of the flight the pilot, called Mike, said he was going to take us down and he tried to find a piece of grass to land on."
