Sorry I forgot about this thread.
http://www.youtube.com/watch?v=wobG_68P_LEAt 0.33, it shows an example from the earlier ones I mentioned and that you posted, freeze it there, and look at how much of the front end blew off, they cut to a mi24 going down nose in, but that is obviously not the same helicopter, even the sky is a different color. Also at 0.56, this is the one I used as most of the basis of speaking to the damage caused. As I stated several times, I realize it's engine damage, and in particular rotor damage, be it chopping off a main rotor or two, or the tail rotor, that brings down these things, but in these cases, the warhead blows the front end of the mi24's pretty much right off. Also, from the time I spend with the EOD guys blowing up the EOD graveyards in Afghanistan, and seeing how much damage a few pounds of c4 can do all on its own, 6.6 pounds of shaped charge blowing into the front, or ANY part of an MI24 has the potential to blow it into large separate parts. There is another example at 1:50 or so, and that helo blow apart pretty well too, at least the front 1/4 of it seems to be adios.
Also the first video I think your google found is one of the ones I mentioned as well, obviously an Afghan fighter in the 1980's shooting at a medium altitude Mi24, the explosion is fairly large, and it looks to me like the rear part of the tail is chopped and folded in on to the side of the helo. It didn't blast it apart as badly as the first video I linked in this post, but the rate it was falling shows it was absolutely in free fall out of control, with the windmilling main rotors only slowing it a bit.
Anyhow, the first 2 examples of the 1st video in the thread is what you were nitpicking over. It is obvious to anyone, especially in the 2nd example that the Mi24 can absolutely be "blown apart", as that is precisely what happened in the video. And as I have said, it may not be the case in every missile hit, or even the majority of proximity detonations, but it certainly does happen. I've also seen the results up close and personal of what a MANPADS missile can do when it strikes a helo with a close proximity detonation or even an impact detonation. Remember what my OP stated, that the Mi24 is a VERY tough bird, and obviously so based on what happened to this one in this particular case. But it isn't invincible by any means, and the three examples I just showed prove this out, that in certain cases the Mi24 can have a large part of itself blown into much smaller little bits by even small missiles like the Sa7/14/etc or the Stinger family.
