This is a 1999 video of a CH-46E Sea Knight landing
on the rear flight deck of the M/V Pecos when something goes horribly wrong.
The Sea Knight's right rear landing gear became ensnared in a steel
safety fence. The pilot tried to power out of the situation and -- well you can see the results.
Six marines and one sailor were drowned. Amazingly 11 others escaped. Marine Gunnery Sgt. James Paige was credited with saving several of the survivors while losing his life in the process.
The investigation of the accident has resulted in the Navy and Marines making several changes to training and equipment in an attempt to avoid a repeat of the incident.
If you are offended by naughty words don't download this as the guy taking the video uses some choice ones.
