My thoughts on reading the opening post were to suggest that you give the Mach Loop a wide berth. Knowingly knocking about in an area of intense fast jet activity is unwise. Entering such an area at low level in a light aircraft is such a bad idea as to be bordering on reckless.
Suffice to say that I also strongly disagree with Gasax' analysis of the Carno accident.
I'm beginning to wonder if it was Gasax or one of his fellow 'why not' brigade who caused me and my crew some lost heartbeats in a similar situation a few years ago in an equally well known military low flying choke point. Coming around the corner at about 75ft AGL to see a light fxed wing head on and very slightly above - I had to descend aggressively to avoid a collision. No evasive action whatsoever from the other aircraft. I presume he never saw us (but I guess he felt our wake a few seconds later).
