Even as a controller, I have to say that it saddens me to see that there are still those who are referring to the scenario as though the T154 pilot could have done much about it.
To be honest, I see both sets of pilot's as though they were rabbits stuck in the headlights of an oncoming truck.
The ATC system appears to have put the aircraft in a very dire situation, and now claims that it is their fault because they ducked instead of diving.
Quite honestly, unless there is some (as yet un-forthcoming) reason why the ATC's attention was not on his Radar Display, providing simple Standard Separation (timeously), I can see no excuse for ATC.
It may well be that over-reliance on MTCD has given the ATC staff a false sense of security.
It is also known that (in ATC) most incidents occur when the traffic levels are low and the ATC is not paying 100% attention to the task at hand.
