The pod is a dummy. Succeeding Loyal's speech test only gets him to tell you that they are VR Training pods, not use them. All conversations regarding the code have only one outcome "pod is for boomers only"
In the G.E.C.K. the pod is stored as "NellisTLpod01"
It has this script " begin onActivate
if ( isActionRef player == 1 ) set vfreeformnellis.iVRPods to 1 showmessage NellisVRPodMsg else Activate endif
end " The condition is pretty much "Check if activator is player" If true show message the message being the "need code" message.
Removing everything and just leaving activate results in nothing happening when you load it up and hit it in game. I think the designers originally wanted a flight-sim mini-game but cut it for whatever reason (time/money/effort). They just left it in there because it took too much effort to take out.
