For special effects reasons, in "TOS", people generally appear immobilized during transport, with the exception of Kirk in the episode "That Which Survives". However, by "TNG", characters can move within the confines of the transporter beam while being transported, although this is rarely shown. Persons being transported are at least sometimes able to perceive the functioning of the transporter while they are in transit. In the "TOS" episode "", the "Enterprise" transporter malfunctions while transporting Scotty from the disabled USS "Constellation" to the "Enterprise" due to a power drain, and Scotty's pattern is nearly lost in transit. As soon as he successfully materializes, Scotty asks the transporter operator with concern, "What's the matter with that thing?" and orders the transporter to be taken offline for emergency repair.
