We don't know how it all kicked off.
His intial calls could have sounded "by the book" and then once cleared inside and inside airspace only then did it transpire that he was a fud. I don't know how often a VFR/ unfiled IFR transit of that airspace occurs. I am sure fisbang can tell us.
Then the controller only had 2 choices try and turn him round or shepard him through all while shoving aircraft towards the tartan hold as fast as Manchester chucks them at her. You can be sure she won't do it again
There might very well be debrief points for the lady concerned and I am sure it will be become a story that trainers will scare trainees on that sector for years with.
So another outcome of this whole incident is that class D which in my opnion was being operated in the spirit of class D ie if there was space and workloaded allowed you got access to it. Now quite understandably, perfectly competent pilots will be refused access in case they do a "vince"
