Seemingly a video of bad airmanship. When you deccelerate like that, the rotor is gonna droop (blades slow down to a dangerous speed). The pilot knew better....and the trees paid a terrible price
A FLIR video from the cockpit of the AH64 Apache helicopter that didn't fit between the trees it tried to fly through. This video is (in)famous throughout the US Army aviation community...
There wasn't enough room on the boats for the helicopters, only the crews. The pilots were forced to fly the just off the boat and jump out, sending the helicopter to the ocean floor.
An SU-27 Flanker (soviet made) fighter jet crashes at an airshow. Notice how calm the guy standing with his back to the camera is at the end of the video...
