Ok, I'll bite:
With the newly imposed rules for us when flying above 5000 feet and the altitudes we have to fly at (East Odd+500, West EVEN+500) for VFR and IFR are at the thousand levels - just to clarify that, IFR EAST = ODD thousands feet, WEST = EVEN thousands feet) and the planes were both at FL 370, it begs the question: HOW!?
The article says they were on a DIRECT HEADON course. Unlike the collisoin over Eurpoe a while ago with the DHL and Russian plane converging.
Why had the initial controller assigned the "wrong" level? Or to put it less harshly: Why was the plane asisgned a level which seems to be in contradiction to what they are supposed to fly at?
It (surley) isn't the fault of the controller who finally had them, but they need to look at how the plane/s were assigned thier given altitudes BEFORE being passed on to the last controller.
