Two of the three girls injured when they fell from a ferris wheel at an eastern Tennessee fair have been released from the hospital. Niswonger Children's Hospital spokeswoman Meaghan Smith told The Greeneville Sun on Thursday that 10-year-old Kayla Reynolds and an unidentified 16-year-old were released. Kayla's 6-year-old sister, Briley Jae Reynolds, remains hospitalized in critical condition. The girls fell from the ride at the Greene County Fair on Monday. Private inspectors believe a mechanical failure likely caused the gondola to flip over, sending the girls plummeting 30 to 45 feet to the ground. Workers were dismantling the rides at the fair earlier Thursday, and the fair will run through Saturday without rides.
