Not long now;
I don't see how you can say that an extra runway would not increase capacity? When we added an extra runway at DFW we increased our landing rate quite a bit. By increasing the landing rate we decreased our delay rate in the hold or the conga line by at least 4 minutes an aircraft. That is substantial.
Now if you have a runway and you don't make it cat III or at least II then you are making a BIG mistake where you work.
