Maybe we should invade Canada and use it ??
We did, a long time ago, and continued to use it right up until we abandoned Goose Bay last month.
The problem there is, apart from somewhat unrepresentative terrain, and frequent poor (read fcuking freezing) weather, is the Canadian propensity to slap a 20-mile avoid on any shagging moose.
We can achieve some things in Canada (winter training being one) but not everything.
On spatially large notams, alot of civ operators do not realise the sheer amount of airspace a fast jet needs, both horizontally and vertically, to perform high-energy manoeuvres. A formation requires even more space. To ignore notams and get in the way of that is sheer madness.
