Lightbulb Moment

That's what I call it when something that previously made NO sense at all, suddenly, and quite unexpectedly, becomes crystal clear.
That happened today at The Castle.

How a perfectly good Iraqi Air Force pilot can make a fatal mistake:

"In American helicopters, the little airplane stays still and the artificial horizon moves up and down and sideways. It is opposite with Russian artificial horizon -- the horizon stays still and the little airplane moves up and down and sideways.

"The Mi-17 has *Russian* artificial horizon."

They're being trained on American helicopters. No wonder this happened. What a tragedy...
