Learn about Station 14-4 KORD + craft Arshavin pass

Two parts: trader dialogue, then a hideout craft. Talk to Mechanic about Station 14-4 KORD to unlock the craft. Then in your hideout, go to the Intelligence Center (Level 1+) and start the Station 14-4 KORD Arshavin K. pass (Restored) craft. The craft uses the damaged keycard you grabbed from the ATV at the Lighthouse blue chalet (step 7). Make sure your Int Center is upgraded to L1 before this step — if it isn't, you'll be stuck waiting for upgrade materials and a 24+ hour build.

The craft itself takes hideout time (real-time hours). Start it the moment you finish the dialogue and let it run while you do other quests. New players: prioritise Int Center upgrades early — almost every story chapter past mid-game uses it.
