There are cameras in the capsule’s for security reasons!! One major reason is damage to the capsule!
The are always monitored by a CM!
To confirm, there is no E-Stop in the cabins! Like the statement was mentioned before, this is a very technical ride. There are 36 other people going through the same experience as you! If there was an E-Stop, the ride would be shutting down constantly!
There is an E-Stop that the CM's can stop the ride for any reason!
In addition, the ride will not start until (1) all of the capsules are occupied and closed, (2) all of the doors are locked and secured and (3) there is no movement for 3 seconds in the capsule area!!
