Thick fog is actually beautiful, if you are outside of it.
How high can those damned things fly?
5000-6000m above sea level.
In the EU it is allowed to fly drones privately no more than 120m above the ground, if you're in a "green" zone (which is out of urban areas, generally).
I cheated and made it 200m this time, since the air was free of any traffic (flightradar.com). I temporarily switched off the transponder that broadcasts my drone's registered ID to avoid any legal consequences, albeit highly unlikely in that situation.
EDIT: The mountain tops in the back are over 2000m ASL, i was taking off from about 800m ASL (which was the top height of the fog, basically).
EDIT2: Ideally, you would do shots like this using a DSLR on a tripod, using very long exposure times with darkening filters. There are only a couple of places for getting that "floating" effect when shot from the ground. I could write a small book about all that, but the key to incredible fog photography is by blurring the fog, while keeping the landscape crispy sharp. Since the thick fog is moving dead slowly, you need times of at least 30 secs to start to recognize the effect. A drone can't stay a 100% steady in the air that long. Would probably give decent results from lower limits, but the "liquid" effect you get on the fog from far longer exposure times is just priceless.
Just google "fog long exposure"
