s and t,
I think zkdli has just argued a point which if true would seem to mean you are wrong, Roffa.
In 2008 it should be possible for a third party pilot or controller analyst to exactly replay the scenario using the original data recorded in the state of the art systems. Evidently insufficient data is infact recorded to achieve this. I am sure that revelation surprises people. maybe NATS is short on diskspace too, or is it more problematic than that?
I don't know which of zkdli's points you are referring to but any "incident" can be replayed, viewed and the analysis started within minutes of its occurrence using more than adequate systems/software that records all relevant (including information downlinked from the aircraft) parameters.
As I said, I'm not getting into circuitous debates with you again. I'll correct anything you get blatantly factually wrong such as the above, but that's all.
