I've heard that on average every plane gets struck once. On the same day that i came back from reus in spain last year a plane going to the same airport was struck and diverted to barcelona. Our flight was delayed because of the storm and we flew past it. It was amazing to see the massive clouds but scary too, very bad turbulence!!! Heres a link to news story. http://www.uk-airport-news.info/glasgow-ai...news-150906.htm
