Not surprisingly in the movie by Fyodor Bondarchuk who fully confirmed the truism that "nature rests on children". Granted, of course, that when your father is Sergei Bondarchuk, a titan of 20th century cinematography with such credits to him as War and Peace masterpiece, They Fought For Motherland or Fate of a Man, among many others, it is difficult to top it. But Fyodor tried (sadly), first by making music videos and then producing vomit-inducing Stalingrad and now he shot the second part of Attraction, Attraction 2 and I would have ignored it too if not for, accidentally, stumbling on this scene.
Even the brief excurse to Kamov-52 Alligator technical data sheet reveals this: The maximum take-off weight of the Ka-52 is 10,800kg.
OK, let's imagine that while this Ka-52 was duking it out with this alien it spent some amount of fuel and some ammo. Let's say it is 800 kilograms. But still, we have a fvcking 10 metric tons of a combat helicopter which when even placed on several isolated points of this glass statically will still break it. Now add here a dynamic of this battle, and suddenly you have loads which are way more than just static weight of this helo. Yet, it still manages to slide down, granted still breaking the glass. I know, I know, it is an alien action movie and it is Fyodor Bondarchuk, but 10 tons slamming into glass roof (however reinforced) and still not falling through? I cringed. What do you think? Is it the case of military and alien porn going horribly wrong?
