Re: how many people on a transporter
Let's not forget "Day of the Dove", in which significantly more than six people were successfully. Also in "The Apple", Spock gets attacked by the Rose of Sharon from Hell and Kirk orders everyone beamed up simultaneously.
"The way that you wander is the way that you choose. / The day that you tarry is the day that you lose. / Sunshine or thunder, a man will always wonder / Where the fair wind blows ..."
