Fantasmic boat catches fire at Disneyland
Jun 24, 2009

As if the delay of the new audio-animatronic dragon at Disneyland's Fantasmic weren't enough, a boat involved in the show caught fire this week during a performance. The Mark Twain steamboat caught fire during a pyrotechnic effect in which flames were supposed to ignite on the Rivers of America. Disneyland's fire department reported no damage and suggested the flames probably would have died out on their own.
