Well spoken. Just heard something on ABC news this morning about looking incidents involving failure of equipment (transponders?) or incorrect use thereof. Comment was also relating to "appropriate" use of ALL equipment on aircraft. Could this also mean using TCAS as the primary means of separating rather than a last line of defence? I wait with baited breath, but don't hold out much luck. There is always much activity but not much productivity when it comes to NAS investigations- something about making the report fit the required conclusion I think. Oh how I hate myself for being so cynical
