Six Flags Magic Mountain roller coaster X2 has been closed for more than a month after two riders sustained serious brain injuries, according to a new CNN investigation. In July, one rider lost consciousness when her head hit her headrest, and now is on medication to prevent seizures after experiecing brain compression and a severe subdural hematoma. Another who was injured a few days later remains in a coma at the hospital. The investigation further revealed decades of injuries since the ride opened in 2002 including two deaths. #sixflagsmagicmountain #news #sixflags
