Having watched the into a few times, I don't see anything that would cause the helicopter to crash. I mean sure, there a few peggies hanging off it, but nothing that would cause it to spin out of control.
You must be blind if you did not noticed the pegi claiming in front of the chopper
A 200 lb man versus a chopper? Yeah, the chopper wins. It's gonna take more than a man in front of the chopper to bring it down. My guess...the chopper was sabotaged.
Yeah, our meat bodies can do a lot of damage to something moving quickly, and helicopter blades are kind of a precision instrument as it is. Even if they were just bent to weird angles, they could mess up the chopper's ability to fly straight.
There are turbine air intakes on the front, he was sucked into those, not the rotors. As soon as it happens you can hear the engines (turbines) going nuts.
