Guests were reportedly injured recently on Expedition Everest when the portable utility light positioned near the exit of the attraction (the holding area of the track just before entering the unload platform) tipped over and fell on a train full of guests waiting to enter the station. The cause was apparently a gust of wind. There's a photo taken by a guest near the rear of the train of the incident, which is floating around, but I'm sure someone else here can track it down.
