[Fly!]

This is gr8t stuff! On the engine, however, I resp. disagree. Guncams from P-47s and P-51s routinely display 50 cal MGs making sieves out of locomotives. They don't explode, like you say, but they are certaintly punctured and rendered useless. 1/2" steel is nothing to a Browning 50 cal HMG.
