I was visiting Cricklade in Wiltshire yesterday and while I was there, at around 6:30/7:00pm, a large thunderstorm came over. VERY dark grey VERY low clouds, torrential rain and forked lightning. During all this I heard a light aircraft flying over quite low, I looked up and saw what I think was an Auster or early tail dragging Cessna. I couldn't see it too well due to the mirk, but it was flying dead South right towards the heart of the storm.
If this was anyone on the forum I would be interested in hearing your experiences of that flight!
