I flew hang gliders for 20 years and I get that once you hook in and locked, you give it a tug. I always did but the ultimate load was when I was doing aerobatics. A simple tug test was really just to confirm you were hooked in. I could always see that I was.

If I could not see myself hooked in, I probably would have second thoughts about getting into that sport and probably would not have made it 20 years without any trouble.

My dad was a pilot in the USAF [20 years]. If I was, the tanks would be full all the time. I would not care if it was for 20 mins or 2 hours. You never know if you fly into a worm hole and enter a different dimension.
