BJCC, you're right about the controller being arrested on suspicion of (what i assume would be) Manslaughter, however it is unlikely that she would have been led out of TC that night, after all the Met would have their hands ful dealing with the ensuing chaos!!!!
The programme itself was in my mind poorly researched and for the most part was aimed at scaring the hell out of the flying public. The scenario portryed, whilst plausible was woefully innacurate in far to many ways to be realistic.
Having read the info on tyhe BBC website, the actress who played the part of the controller ad libbed a lot of the time, her research was poor to the extent that she couldn't even manage to get the names of the holds right or even use standard phraseolgy (as per MATS 1 app E)
There then begs the question of corporate manslaughter, you can be sure that the Police would be looking at the procedures and if they were the cause of the accident then those on high have to accept a level of responsibility.
As it was the whole thing was nothing more than an attempt to scare the ill informed flying public.
When I was at the college of knowledge, a documenatry team approached NATS with a view to doing one of those fly on the wall programmes on ATC and in particular ATCO training with a view to following the careers of a few at CATC from Highfield Park through to unit validation.
Perhaps if NATS had not declined the offer then maybe joe public might realise that we're not the ones with the ping pong bats, we are highly trained professional people who take great pride in the work that we do, and that flying is SAFE because we are part of the team that wants to get them from A to B SAFELY.
