PORTLAND — The pilot of a hot air balloon is in satisfactory condition after suffering second-degree burns at the Great Falls Balloon Festival in Lewiston Saturday, said a spokeswoman for Maine Medical Center.

Andre Boucher, who was still at Maine Medical Center in Portland late this afternoon, was one of five people injured when propane ignited as Boucher was charging a fuel line.

Boucher’s injuries — second-degree burns to his arms, legs and face — were the worst sustained in the incident, according to Joshua Shea, a spokesman for the festival.

About 7:10 p.m. Saturday, within minutes of the balloon’s scheduled take-off, a backup of propane came into contact with the burner and ignited.
