ALBUQUERQUE, N.M. (AP) — A balloon basket caught on fire, separated from the rest of the balloon and crashed during the city’s annual hot-air balloon fiesta today, killing one person, a balloon fiesta official said.

Two people — a pilot and a passenger — were aboard the Wings of Wind balloon when it crashed north of Albuquerque, said Kathie Leyendecker, a spokeswoman for the Albuquerque International Balloon Fiesta, held each October.

She did not know whether it was the pilot or the passenger who was killed, and had no immediate word on the condition of the second person.

The yellow, brown and orange balloon was shaped like an upside down triangle and was among hundreds of balloons participating in today’s events at the balloon fiesta, which runs through Sunday.

Ambulances arrived quickly at the scene of the smoking basket, called a gondola, witnesses said. A New Mexico National Guard Blackhawk helicopter touched down later near where the balloon drifted to the ground.

A witness, Alan Manning, told The Associated Press he saw the basket in flames and saw things falling from it, but could not tell if they were people or the propane tanks that fuel the hot air balloons
