The situation at Eastern is this:
Ops at eastern don't realise how bad the weather is at airfields. There are several reasons for this; often the person running the airline early in the morning may have little more than a couple of months worth of experience, they are overloaded and undertrained and not supervised. Not their fault though.
The crew ring and tell ops it's foggy at the destination, the person answering the phone will then seek advice from someone with more experience if anyone else is in the office yet. If not they ask the captain what should be done.
If they are being supervised and it's a certain mr Hburger it will then depend on how much the vein is throbbing in the side of his head, how his general stress levels are and if he has done his deep breathing relaxation tape on the way to work. Usually crews are told to launch, I believe because the person telling them to go has no clue about minima, go rounds and they are all scared of getting a bollocking for having aircraft on the ground. Once an aircraft has launched then it is the captains fault if he or she can't get in.
