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

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

Boucher’s injuries — 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.
