Some would scream that showing these sort of pictures and videos is vile and gruesome. I disagree. Shock factor may be the difference to saving someone elses life. As those who work around aircraft will know, people tend to leave their brain behind when near an aircraft (literally in that guys case) and have little concept how dangerous the environment really is. If something like this sticks in their mind when everything else is forgotten, then its done its job as a warning.
