A funnel cloud/mini twister over the Lake District last week. I was flying from Kendal to Carlisle over the fell tops at 2800' and saw what I thought might have been a small funnel cloud about 2 miles off in our 11 o'clock. Cloud base was around 3- 3500' and CBs had been forecast.
Curiosity got the better of me and my colleague and we flew to within about 6-700m to have a beter look. It was definitely a small funnel cloud, maybe 300' long, but with little obvious rotation and it began to disipate as we approached, before forming again as we flew away. Perhaps not my smartest decision, but fortunately no harm done.
One of those occassions I wish I'd had my camera.
