The cold front did not clear until lunch time, and then only to showers and a very strong blustery westerly wind. So no flying.
The few of us at the Thursday Morning Tea Drinking Group gathered around the computer to work our way through the new "Safe Winch Launching" bit on the BGA website. Watching the video clips of simulated winch launches not reaching their wished for final outcome bought the point home. Working through the quiz was a very useful tutorial.
We then had lunch and went home.
