Driving on to the airfield at 9am I couldn't even see the wind sock in the mist. So I thought it would be a pretty short day as Duty Instructor: just show my face, cancel the trial lessons and head back home for coffee and brownie points. However, by 9.30 the mist started to thin and we got the kit out. Flying from the south end, the first few flights were really spectacular - launches to 1,600', about 1,000 above the broken cloud with amazing views over a solid cloud sheet extending way out to the west from the airfield boundary. We were also treated to full "broken spectres" (Google it if necessary) on the cloud below. It's probably best not to tell the CFI about how we were going into cloud on the base leg (we had the ILS on). Anyway, the cloud quickly cleared and we enjoyed a very pleasant day's flying in the sunshine. Darren rigged his LS3, Ken entertained us doing his annual checks and Sarah Z munched her way through an entire packet of extra strong mints in three flights. The visitors also enjoyed their flights with Eugene and Matt - one was heard to say "My gob is completely and utterly smacked!" , Thanks to Phil and Mike for some great winching.
