I agree with that. I would guess that Vulcans might more commonly not enter TNZ in the test. I think it is helpful to Starfleet as another psych test, to see what type of potential Captain that cadet would make. One who doesn't enter TNZ might be more appropriate assigned to a Science or Medical ship. And it's not a bad thing - all types are needed.. I'd actually argue that you wouldn't automatically fail for not going in, since the first instinct in a computer simulation would be to take risks that you wouldn't if your real life were on the line (but, at the same time, there wouldn't be much to judge, so you probably wouldn't get top marks).
Well played. The Klingons would likely say the same just before firing that last volley.I would warp to the KM, then when the Klingons appeared, I'd stealth-launch my most powerful small craft (shuttle if necessary, runabout or captain's yacht if available), and lead the Klingons away at warp while that ship put a tractor on the KM and towed it out of the Zone.

I wonder if it was possible to get any survivors out. Warp in, beam them over, put them on shuttles/escape craft, and hold off the Klingons as long as possible, along the lines of Captain Kirk Sr.
