Jon Shirey, the Reedy Creek Firefighters Association president, told the Orlando Sentinel that the call initially came into the fire department around 6:45 p.m. as an electrical fire on a junction box outside the castle.
A tree next to the junction box caught fire, resulting in the evacuation of Cinderella Castle.
Firefighters initially reported that a firework appeared to have caught the tree on fire, but no fireworks were launched during that time. The official cause is still under investigation as it is unclear how the junction box started the fire.
Though firefighters avoid driving through main areas of Disney’s parks when possible, the nature of the call caused responders to drive down the Main Street area of the Magic Kingdom, Shirey said.
