Bear Cub - whoever you are, I have presented the facts as I recall them. If you choose to disbelieve me that's your privilege, but why should I lie in an anonymous forum? I spent a long time afterwards going through all that happened and couldn't find much I could have done differently bar possibly trusting the Met Office, which is a habit that has got me into trouble once or twice (on the other hand more often it's had me cancelling flying to end up doing DIY on a perfectly flyable weekend).
I recalled the incident only to illustrate the changeability and predictability of British Weather - something I think I adequately proved.
