regarding your question on the airspace closure last September in Canada
I was on duty that day and as far as I am aware the Muchachos were still flying. The airspace closure was arranged under an old NATO procedure (ccooked up during the cold war) called SCATANA and as far as I am aware only the USA and CAnada were signatories to this as the only place the Ruskies were likely to come from were from the North (over the pole - the yanks always felt the Canucks were expendable) not from south of the border.
Hoope that explains that for you.
