Sorry, Truss has just killed any plans for reform stone dead, kaput, finished.
Truss used the words "By the end of the year" referring to the Governments response, which has a very specific meaning when it comes to politics; it means "in the period between 25th December and 1 January".
This time is reserved for the release of unpalatable information, most probably in this case, the Governments outright rejection of most of the recommendations. Everyone is on holidays including all the journalists and all the aviation peak bodies. This means that there can be no credible industry response till mid February at the very earliest, by which time the Governments response is old news and in any case industry anger has evaporated. Its difficult to "maintain the rage" when you are on holidays, sunning your self on a beach somewhere.
What happens in mid February is a little lukewarm industry angst at what might have been.
The public servants will say the are already implementing it and simply tell you to move on and "try again in five years" as the saying goes.
Folks it's over. We are watching a classic case of a bureaucratic fighting retreat. The iron ring will write a volume on why each of the recommendations is flawed and unsafe, they will simply wear Truss and the new DAS down with paper. This is why you need someone from PMC to head this mess - they understand about file stuffing and other tricks. Truss and his staff do not. A PMC person needs to send the ring packing on day one. If that isn't done, the embuggerance willl continue unabated.
