Nomde plume, no, you specifically said that traffic wasn't given. Not that traffic wasn't given on the ground. If that's what you meant how about you construct the sentence accordingly.
I'll say it again, they may NOT have been denied a clearance in Class E if a procedural clearance could have been issued.
I've read the preliminary report, it means 2 tenths of sweet **** all. It has NO information in it that you can construct a cause from. There's nothing to 'uncover' from a preliminary report. In fact I don't know why they're published, it serves no purpose.
