As an experienced current LTMA controller who does a fair share of nights, I think I am more than qualified to talk about what happens in the TCR in this day and age.
If I or any other controller happens not to have an aircraft on frequency at that moment in time, we will not be watching the radar. The loud-speaker will be on, a handset set up to transmit and we will be reading a book, or chatting, or catching up on admin.
I have already said in 2 previous posts that the liklehood of a jet or even a C130 doing what was postulated is remote.
Please don't try to tell me how that Ops room works, I know because I work there... not 'used' to work there. And yes, you are correct it is getting silly, because people who do not have a clue about current working practices or the current Ops room layout try to tell people who do that they don't know how things work!
