The National Transportation Safety Board has recovered a TransAir Boeing 737-200 from the ocean floor just off of Hawaii. The aircraft that crashed exactly four months ago was resting on an ocean shelf between 350-450 feet (106-137 meters) from the ocean surface. The mission to recover the plane took place throughout October. Having an aircraft is a huge boon when undertaking air crash investigations. From the aircraft's black boxes to individual components, having plane parts can help investigators piece together precisely what happened to a downed jet. However, recovering an aircraft that has split into two seems to be easier said than done when it's at the bottom of the Pacific Ocean.
