Hour 2: IX.T.9 - smaller hangar (broken plastic oar)
Hour 3: IX.T.9 - smaller hangar (transceiver upgrade - a clip-on case, matte blue with a stylized palm tree engraved on the back)

There's a small room in the back of the hangar, much like in the larger one, which is currently full of junk but could be cleared out into a closet-sized office of sorts.

Hour 4: IX.T.9 - smaller hangar (aluminum sign - blue rectangle with a big arrow on it pointing to the right, letters underneath are too scratched and faded to read)
Hour 5: IX.T.9 - smaller hangar (six beach plums)
Hour 6: IX.T.9 - smaller hangar (tarp, mostly intact)
Hour 7 - 8: IX.T.9 (prepping dinner)

It's now the start of Night 006. Based on his search request, K will wander into the airfield just before sunrise, around hour 7 of Night 006.
