I was next to a helicopter running on the ground which let go an integral piece of a blade that took off the outboard section of the blade. The transmission was snapped in half and the rotor, mast, swashplate seperated climbed 100 feet and then came down not 30 feet from the ship. It happened so fast the pilot reported no vibration. When in flight the rotor was stable as it rotated around its new cg.
