go no go!
Sadly this reminds me of a gliding course I went on some years ago. We had perfect weather and 100% aircraft serviceability. Despite this I did not get to fly until the third day of the 5 day course and on the Friday the instructor did a "lead and follow" excercise. He went first, the winch went bang and took 30minutes to fix. By the time we got up there he was WELL gone. Me and another er sucker landed back on the ridge, had a brew, gave it up as a dead loss and went home.
It's called customer care in other businesses. I worked out later the flying costs per minute were greater than fast jets!
Amazingly they rang me up next year to see if I wanted another course!
