These are the buildings I've worked on today:
So let's start with the first one, that would be the engine testing facility. It has some complex structural stuff going on which I still need to build, but the parts at the back are good now... Now I've been in there once, got there with an Airport tour. The wind in there seems to be really bad, but ofcourse it's ment to withstand the thrust of jet engines.
Next to it is the old LTU Hangar 8. As far as I can remember I've only once seen the LTU fleet, as in before 2007. Since then the airline has been taken over by Airberlin, hence their present hub at the airport, and therefor all their assets (A320s and A330s aswell as Hangars) have been registered under the Airberlin name. Currently this hangar is fully owned by Airberlin, and I've seen numerous A330s come out of there or go in. Also I've once noticed a Lufthansa A340-300 being repaired there, which I found odd...
Then there is the shared Hangar next to it. It's fifty percent owned by LH and fifty percent owned by AB. Therefor both companies repair aircraft in here. If my memory serves me correctly there used to be, and there still might be, an old LH Vickers aircraft standing in this hangar...
As far as things go I have, unfortunatelly, never been inside either of these hangars...
Keep in mind though that detailed worked still needs to be done...
