I refer you to the AAIB report (Formal Report 5/2010 published September 2010) on the Tutor/glider midair near Didcot in June 2009 which included a chart of the traffic density near Abingdon on that day. The Brize/Benson gap is one of the busiest pieces of Class G in the country. And it appears that the said gap is being closed for 3 days.
This is serious for GA. As commented, it appears possible for the system to impose this RAT without the slightest comeback for all the other airspace users affected. Democracy in action???
