M609
Nice idea, but that would take out a large chunk of airspace in a small and, aviation wise, crowded country. It just wouldn't be fair on other airspace users and, contrary to popular opinion, the military are no longer the majority in that case.
The whole question for protection of IFR procedures, not just for the military but for civil units without CAS, needs looking at. WBS and I both feel the same way - it is time the UK just tore up the airspace map for this country and started with a clean sheet of paper.
