As much as I identify with Dr. McCoy, I'd have to give it a whirl at least once.
I'm still amazed by how McCoy's reluctance and misgivings about the transporter are mockingly ridiculed in TMP even immediately after a fatal transporter accident.
Who in their right mind would willingly step into the same machine that just mangled two of the crew. Or more properly how could Kirk haughtily order him to do it,
especially after arriving via travel pod himself, specifically because the transporters weren't working.
What's still odd, of course, is that all three transports in the film imply the need of a working transporter pad at not only the origin point but also the destination.
