Somebody who saw the script for sure said the line was supposed to be "someone is beaming down from the ship"
And Takei misspoke and said the "bridge"
As I said, I am sure the last time this was brought up, someone did check the shooting script. Of course, some online scripts are transcribed from audio.
The JA Lawrence adaptation for Bantam is corrected. It says:
The air was shimmering. A familiar shimmer, but erratic and uncertain. “Someone’s beaming down from the ship.”
Someone was certainly trying to, but there appeared to be some obstruction.
Willing the transporter to operate, as if that would do any good, Kirk waited. The shimmer faded, erupted, faded; with one last splash of sparkles, Spock materialized in front of them.
I recall this episode has numerous errors. At the last minute, Barbara Baldavin suggested that "Mary Teller" become her previous character, "Angela Martine", but Kirk calls her "Teller" before the name change, and then later her new boyfriend calls her Angela.
