I was at the Cosford Airshow on Sunday and took a lot of photographs. Some of the better ones are on Flickr.

One thing that I noticed when reviewing the shots back on the laptop at home was that most of the pictures that I took are not as sharp as I would like. My old 75-300 (non-IS) lens significantly limits the quality I can get in these situations. Time to think about upgrading (when the financial situation improves!).
