A hot air balloon exploded and landed in Temecula Saturday, injuring four of its five occupants, according to the Riverside County Fire Department.
Fire Department spokesman Mark Annas said the balloon exploded shortly after landing.
One person was burned and transported to a regional burn center while two others were badly hurt and taken to local trauma centers. The fourth injured person was taken to an area hospital.
Officials said the "uneventful landing" happened shortly after an explosion. The balloon crashed at the corner of Vino Way and Calle Cabernet at about 7:44 a.m.
The National Transportation Safety Board is investigating the incident. NTSB spokesman Terry Williams says officials are interviewing witnesses.
