Jackbauer - what on earth are you talking about? This is absolutely nothing to do with a Ryanair employee / contractor exodus - but FL410 to 250ft is not what was being questioned. As has been made clear to you by other more informed posters, that is not unsafe. Nowhere does it say that they had a high rate of descent in the latter stages of the approach. Where they screwed up was continuing the approach without being visual with the runway which was a serious and dangerous decision.
But the rate of descent from FL410 and unstable approach you continue to go on about is nothing to do with the investigation.
Please get back on topic and if you've got an issue with the way Ryanair aircraft are flown, raise a new thread. With 1400+ flights per day, the odd cock up does happen. No excuses for their poor decision making though.
