Where do you land at logistics depots?

So I took a hauling mission last night that was Port Tressler -> microTech Logistics Depot. Okay, easy enough. I get to the logistics depot at night and flew around for a couple minutes looking for a landing pad. I found one near the top but it was for the main entrance, not unloading cargo. Then I hit an invisible wall trying to leave and blew up. Where the hell are you supposed to land at these? It was night so I couldn’t see shit except red lights and rain.
