Actually...height alone is not the criteria..
In this case just as in the London 109 Crane collision proved....track and height combined with visibility determines appropriateness.

There was a bit of a breeze blowing - watch the smoke from the crash - and from my met theory from 1970 I understood that fog won't form in a wind.
So maybe this is low cloud blowing onto the hills, and the lazy ground-based reporters called it fog?

Fog or low cloud....with poor visibility.....are ignoring the simple fact it was the lack of being able to see and avoid the obstacle that is most likely cause based upon either the official forecast or the photo's being posted.

keke - AC was referring to radiation fog with his comments about wind - I think you'll find he knows plenty about the other forms.
MG - Istanbul Ataturk does not allow IFR rotary traffic so this ac would have been flying VFR, in theory along a set route and thus collision information unlikely to be passed.
Nowherespecial.
Should it have been allowed to take off then. Maybe out of limits but may have had SVFR approval if on approved low level route. Surely the Local radar would have all A/C on the screen and seen what might happen. My View.

I don't think the ATC would have been paying much attention to it, from the little I know of helicopter ops from that airport.
The area to the North of IST is very much different from the environment at IST. About 5km north you have rolling hills up to about 700' AMSL (IST is about 10' AMSL) with dense vegetation and forests. It absolutely 100% has it's own microclimate there. If they have no specific weather info from the area north of IST (and there are no airfields there so there is nothing accessible) then I suspect you could easily find suitable weather to launch at IST and a situation not close to being VFR in the region to the north.
IST is one of the world's busiest airports, a FW ac departs there every 50 seconds and lands on a different runway at roughly the same interval. The controllers hate RW traffic there as it interferes with the FW too much. From memory there is a speed restriction coming in of about 160kts minimum, hence no IFR for RW. Basically once the RW depart the ramp up by the VIP/ GA terminal, no one cares what you do and no one is really watching, certainly not in real time.
Just my experience of the area though.
