Well hopefully we'll get an alleviation to greater freedom soon but for precedent I did my health flight earlier this week and got stopped by the Police en route to the airport. They politely asked where I was going and I told them I was driving the fifty miles to my field and that I would be conducting an hours solo local flight in accordance with CAA/Lycoming's guidance and then buying some food on the way home. I also added that I'm 66 with a recent history of Cancer and that in all other respects I had been, and would be following lock down rules.
The lovely young female PC replied that it was fine and the best excuse she'd heard all day. It apparently beat 'Going to Aldi' hands down.
