I distinctly remember the morning we went to move the S61 out of the hangar(I was on the head to turn the blades) - lots of head scratching and swearing. We then released the pressure from the oleos - then the tires - more swearing and head scratching. Voila - dig two trenches !!!
Even then we had to cut out the front hangar panels to allow the beanie and Pitot to pass through.
