After the run of scrubbed days it was good to have a flyable day in prospect – even with a lively cross-wind. Second launch, with Carol P and Paul P, demonstrated there was lift available with their 28 minute flight but nobody else was getting anywhere close. Couple of hours later Peter E disappeared in HZD for 3 and a half hours (longest flight of the day). My attempt to introduce a work friend to the joys of silent flight resulted in a 4 minute flight, landing reciprocal (shortest flight of the day). Second attempt was more successful with climbs to 3,800 and heading back after an hour. 3 other hour plus flights, 24 launches and 13 hours flown in total.
