Today, I had one of the most interesting flights in my flying career. I was flying out of Black Diamond/Cu Nim (CEH2) in Alberta.
I took up the father of two of our youngest students for his first glider flight. It wasn't planned and the conditions didn't look promising, but our high-performance two-seater, the DG1000S, was available so we launched.
We released at 2000' above ground and flew around for a while and were at 1000', preparing to enter the circuit, when we entered a strong thermal which allowed us to gain 3000'. This height (7700' ASL) allowed me to demonstrate the high-speed performance of the DG1000S and before descending, we moved upwind to get away from a rain shower that was passing over the field. At was at this point, we saw the most remarkable double-rainbow, below us!
