After a week of cold frozen surfaces, the rain on Friday had turned the top 2" into a bit of a quagmire, but as usual the airfield had started draining quite well and it was pronounced an aerotow-only day. The first launch to 3000ft with Stu and Jack found some gentle wave after a couple of loops. We then had to stop for a fairly heavy rain shower and dark black clouds. After lunch, Chris C showed Phil some perfect loops (as you would expect from an ex-fast jet pilot). The third aerotow had to be abandoned as the canopies would not clear in the cooling humid air.
