I started the day getting up on the roof to wash the solar panels. Well, first I dropped the ladder on myself, bruising my shoulder and elbow. Then I found that the window washing stuff that I'd used last time had either leaked out or evaporated away. Bugger. I managed to put the squirty hose nozzle back on, but didn't have the usual bucket of soap with me, so I just rinsed them off... that'll do for now.
In the early evening we went to Lincoln and took the Flightstar out for a tootle around the area. It was cooler than it's been recently, so the plane flew quite nicely, plus it wasn't so bumpy.
