All was going perfectly until…
… I decided to leave the peachy-looking line of clouds pointing rather nicely towards my goal (Reading) and join my chums a tad further south. It was pretty much a straight line to the ground as soon as I made that call. Why?
Compared with Alex Kennedy, who flew pretty much the same line initially and only 15 minutes after us, our whole gaggle of 6+ pilots decked it within 20k while he went on to fly nearly 60k to his goal (have a look at his tracklog on xcontest - no links allowed here). Now granted he has far superior skills to me, but we flew at the same speed, got to the same altitude, had the same climb and descent rates, but he found the next climbs whereas we did not. I have a theory!
Sea breeze. Something we don't generally suffer from so far inland and therefore know little about. I'm certainly no expert, but the messy looking edges to the clouds might have had some sea air about them. There were certainly no climbs to be had by any of us, whereas Alex stuck to his line and joined the dots.
It's a fascinating game and we (can) learn from every flight. Next time I'm following Alex!
