R44 Crash Rowlett Tx  

I can pretty much tell you what it is like. Flying a Navy H46 over the Eastern  Shore of Va in early 1970s. At 1500 ft and 110 Knots did an uncommanded loop. On the way up went into a Hi g pull-up, cyclic did not respond. Tried rudders to roll it but nothing. Yelled at copilot to switch hydraulic systems think maybe a hydraulic problem with flight controls. Nothing. approaching upside down thinking if I could keep positive Gs on it I could bring it down on backside of loop. When upside down rear blades cut most of front blades off and cut helo into three sections. Very violent. Cockpit section finished loop and freefell spinning from about 1800 feet. I remember putting flight controls with, instead of against, the spin thinking maybe controls were reversed. Overhead CB panel broke loose, cracked my helmet and knocked me out. Broke both lower legs on bottom of instrument panel. Lots more to my story but my guess is most pilots work their butt off trying to save the aircraft. As a famous pilot, Bob Hoover,  once said " fly the parts to the ground".
