On Bring-A-Friend free day at KI, me and 7 of my friends went up there. The lines were very LONG, but we expected it. We decided to pick 2 rides to try and ride before closing. Tomb Raider, and Face/Off. We rode TR and then headed over to F/O. After about an hours wait, we finally got on. We were lifted by the hill (I started facing backwards) and released. We did the 3 inversions, then went up the hill. We came back and did the inversions again. We sped through the station, and just as the ride was supposed to be over, and be slowly lowered to the ground, we didnt. The ride kept going up the hill, back up the half loop, then come down. We went back and forward about 4-5 times. Anyone know what this is caused by, and why it does it?
