Yes, energy is also expended holding the plane up. It was implied when I said energy use was at a "minumum"

Your science on the sonic boon effect is more accurate. The air flow over the leading edge of the wing does not necessarilly ever reach turbulence but approaches it (I didn't use the T word, I don't think) and I know there is laminar flow accross a wing beyond the speed of sound.

"Recall Newton's 3rd Law concerning action and reaction; if a wing is pushed upwards by the air, in return the air is being pushed downwards by the wing."

What I recall is that the wing "lift" is off the top surface of the wing, air pressure pushes up from the bottom. Aren't you thinking of a helecopter prop?

But I stand by my analogy that shows how energy can leave a bullets typical influence area as a shock wave and cause lateral damage that adds to killing power. You've pointed out the downside when using analogies. Thanks for your comments.
