I'd like to point out that the people who are saying "yes" are all presuming it'll work at 100% efficiency... all those parts made by the lowest bidder. Hell, it doesn't always work in the 24th century, 200 years after its creation. And we're talking about the first one available for public (Human) use. "No, you won't feel any pain, your pain receptors will be reduced to atoms and scattered across thousands of miles."
The transporter KILLS you and then creates a perfect duplicate of you somewhere else, a duplicate who has every single one of your memories except the moment of your DEATH. That's why people in the Star Trek universe think that transporters are safe. It's because people DIE every time they step onto that thing, but they can't warn anybody.
One word: irrelevant. They either work or they don't work. When they don't work, nobody goes anywhere.
That was a costly operator's error. It would otherwise not have happened at all if someone had been paying attention that the Enterprise's transporter wasn't working right--it's the reason why Kirk boarded the ship by travel pod. Any other time, if the transporter was faulty, no one would be beamed anywhere until it was fixed as was the case both before and after that incident.
What about Evil Kirk, the Mirror Universe, Sisko, Bashir and Dax who were accidentally transported to the year 2024, by an explosion in a microscopic singularity while passing through the solar system at the time of the beam-out, or how about when most of the command staff of DS9 were tranferred to the Holosuite as holograms, Tuvix, Weyoun 5... just sayin...
Nice try, but those were generally the result of "weird spacey stuff" happening and no one died during those instances except for Weyoun 5 (which appears to have been a deliberate act of murder). Evil Kirk and Tuvix were successfully reintegrated to their original selves. And the transfer of DS9 command staff into a holosuite was done to keep them alive after a runabout explosion.
Either way, just to be on the safe side... I'd wait for the second model to be cleared for public use.
Remember what I just said. The episode "Realm of Fear" proves that the transporter does not kill you. This is because we see that Barclay's consciousness is uninterrupted - from the moment he steps onto the pad until the end of the transport. And he even sees things while being transported.
??? When was it ever stated on screen that the original is destroyed? Quite the opposite, if you look at the writer's guides and novels.
Which, of course, is impossible if your body is dematerialized. Even if the consciousness can somehow exist for a split second while the brain is disintegrated and re-constituted, how can you see without eyes and optic nerves? At any rate, if we accept the existence of transporters within Star Trek's reality, it stands to reason that they'll never be 100 percent safe and reliable. Nothing is.
This would have been a lot easier to explain if they had just made the transporter move people by warping space, like ships do with warp drive.
