Old Carthusian
It is difficult to be churlish with one who admits to being old. I do not share your consummate confidence in AB and AF. BEA and the Judicials, perhaps. BEA has done as expected, no comment. I think there are at least a few in the Boardroom of ABAF who were ready to......."Move along, nothing to see here"
AF, for example had to look at the threat of a strike to replace equipment it was ordered to do prior to 447's ill fated recipient of the very thing addressed by the equipment changeout. UAS or not, AirBurst or not, etc., action is not (was not) done as precautionary, or even as required, and it can be argued there were dead people due a dragging of the feet...... Yet you insist AF and AB were Johnny on Point to find the evidence of an accident they likely had a hand in causing?? Not sensible prior to argument.
