Ah yes, we did indeed go back to doing air-to-mud after the South Atlantic experience.
The 'Vulcan cannon' was a lot easier to get a decent score with than the Hunter's Aden. But you didn't get the smell of cordite coming through into the cockpit!
I suspect the main reason apart for the flatter bullet trajectory was that the LCOSS was better than the old GGS when it came to shooting at muddy hessian.
But these days, I suspect that the expression 'lessons learned' is not an acceptable term with which to confront Their Airships. Not enough of a biz-speak w@nkword ring to it, for one thing....
If flexibility is the key to AirParrh, "...then indecision must be the key to flexibility!". As was once so rightfully commented by our USAF exchange officer!
