Might not help much, but maybe we can ask the dragons if they know anything about airport. They knew its location beforehand, so they must know something, even a little bit might help. As for specific rooms to look for, I think that's kind of obvious but I'll point it out anyway. Libraries, foundry, warehouse, archive, etc. Search for records logs, airship/golem blueprints, any and all forms of weapons and tech. And best to proceed with caution, stay alert for any booby traps and hostiles.
Here's some advices, up for grabs and changes if anyone deem it necessary. Open to other ideas if these are sufficient:
Find/disarm any booby traps & defense mechanisms, mark areas that are safe (74)
Look for archives. Search for records, logs, books, blueprints of airships (74) (Posted this advice myself)
Look for foundry/warehouse. Look for weapons, golems, tools & technologies (74)
Look for hangar bay. Find and inspect any airships found. (57)
