Fallingwater: I removed this -> "This video shows how quickly it all goes to pieces if one of the rotor blades hits something." <— because the video has been deleted by the user.


Scrounge: As much damage as it would do to the hellicopter itself... I'm surious, would the blades at least go through whoever was in them, or would they break off completely?

Fallingwater: this is just a guess, but based on viewing this http://www.youtube.com/watch?v=MSUgp7Cm1N0 and this http://www.youtube.com/watch?v=3F2k-GWKW-w , I believe what would happen if a hypotetical single blade hit a human would be the sudden projection of said human a good distance away, with lots of bones broken and very definitely dead, but probably not cut in half. Along with the human would be projected the pieces of the blade that hit it.

If you consider things from a practical point of view, though, a rotor isn't made by a single blade. If a human got into slicing range they would maul him/her very badly, and maybe even manage to very roughly cut him/her in two if the rotor was advancing (and thus keeping hitting the human as the outer bits of the blades disintegrated), the helicopter would then drop like a stone.

Again, keep in mind this is all conjecture, and I might be horribly wrong.

Update: hey, turns out I was horribly wrong! Helicopter blades are perfectly capable of cutting hard stuff, so a human would be diced very quickly indeed. However, the helicopter doing the dicing would still very likely drop like a stone. Very small objects might even be cut with no dire consequences. Here is the proof (0:50, 1:03).

Kizor: There was a helicopter crash in the filming of a Twilight Zone movie that decapitated the male lead and a child actor, in the latter case taking a shoulder and an arm off as well. A helicopter crashing into a French restaurant in January decapitated two. Aren't you sorry you asked?

Another interesting Real Life example: when Your Obedient Serpent was in the United States Coast Guard, our ship's helicopter had an engine flame-out and hit the water. The rotors, bent down suddenly by the force of the impact, sheared off the tail of the helicopter before breaking off themselves. (Nobody was injured, and the Pelican helicopter stayed afloat and upright for over a day and a half, until a Navy salvage team managed to capsize it.)

Tongpu: removed irrelevant commentary.
  • The lesson here would be that smoking kills?
    • No, if he had been smoking (rather than chasing) the cigarettes, the whole incident could have been avoided.
    • That's reverse logic. The Aesop suggests that as a smoker, you'd want to chase the cigarettes in the first place. In other words, it's the cause of being a smoker that gives the result of death. Another fault is that I see no logical need to smoke in order to avoid turbines.
