The sailors were aboard an MH-60S helicopter when they crashed into the Pacific Ocean on August 31 (file photo)
* A crash summary document reported on Wednesday that the MH-60S Seahawk helicopter crashed due to 'side-to-side' vibrations, killing five navy sailors
* It remains unknown as to what might have caused the vibrations on August 31, 60 miles off San Diego's coast on the USS Abraham Lincoln aircraft carrier
* The Navy were finally able to identify the five sailors killed in the crash but their bodies remain missing
* The sailors were conducting routine flight operations right before the crash happened, the Navy reported in an on-going investigation
* Only one crew member who was aboard the MH-60S helicopter was rescued as he is now in stable condition
A brief Navy narrative of a fatal helicopter crash off Southern California said the aircraft experienced 'side-to-side' vibrations that caused the main rotor to hit the deck of an aircraft carrier while landing, according to a Department of Defense report.
The MH-60S Seahawk fell off the deck of the USS Abraham Lincoln on August 31.
One crewmember was rescued and five were declared dead after a search. Another five sailors on the carrier deck were injured.

WNU Editor: I thought the helo crashed in the ocean. Apparently not. The crash occurred on the deck of the USS Abraham Lincoln aircraft carrier where it then fell off the side of the ship into the ocean. I suspect there is also video of this accident.

Bearing or some part of the frame was loose? This is going to get interesting for maintenance.
One bulldozer operator told me he drove his bulldozer using his butt. That is not to be raunchy or anything. He was using the nerve endings his butt to feel the vibrations of the dozer. If you dig in too much the frequencies are different. The blade of a dozer can bite too deep into the earth. When you did that you can flip it onto its side.
They use sound waves on structural steel to find cracks in welds in the factory.
Something obviously came loose or was working loose. The thing is should maintenance have known? Wonder if the bolts were greasy.
Thanks genius, we all have ridden bikes and cars and understand vibrational and acoustic differentials are helpful for navigation
In fact, your ear was designed for this and so much more, including balance without eyesight
And I also don't think anyone here is unaware how sound waves, among other things (eg current differentials), are used to find micro fractions
Say something new :)
Just teasing you ;)
But yeah I too thought they crashed in the ocean...
Likely a maintenance neglect/ human error
If it was so bad that it basically lost mechanical integrity, I'd say that calls for an investigation into maintenance crew and protocols
Secondly it could be a material defect, but I almost doubt it.. it's too unlikely to occur, I think, but then even if it was a structural thing it should've shown up at maintenance checks
RIP
In one factory they only solved the problem of finding hidden weld cracks with sound waves in 2001. So apparently not so east or widespread.
If it were widespread, why isn't on your car?
