We marched them up to the top of the hill........ and we marched them down again....... Not quite 10,000 members but a good number who were all desperate to fly. The field had drained, the sun had come out and there was a light north easterly wind. The gliders were all positioned at the far end and then there was a quick lunch stop but unfortunately, the sun's small amount of heating just had the effect of stirring up the near 100% humid air, causing cycling of low cloud at field top height throughout the day.
