also, in Levski, if you took too long to land, it might screw up when you try to take off. What it does, it'll rubber band you at some point back inside the hanger. You might be just lifting off, or exiting the landing bays when it happens, or you might even be well on your way, 100 Km away at full throttle. Just be prepared for it, or you might end up bouncing all around the hanger.
It's a known bug, and they're working on it. Survival tactic that sometimes works: The ship is bouncing because the physics model says it has momentum. In extreme cases, when this happens you can end up rather disoriented and cause more issues when you try to recover, so the best advice is, whatever you're doing, stop it.
There is advice from something that Air force pilots say about flying during emergency situations:
"It doesn't matter what just happened, you're the pilot, its your job to fly the damned plane, so fly the damned plane".
Edit: One other thing... sometimes there's a warning. It's a double beep sequence, like "BEEP beep, BEEP beep", or something like that. You'll know it the second time you get it. FYI too, the same thing can happen anywhere you need to request landing, it's just more common at Levski.
