I wouldn't worry too much Cater; unless there's an unforseen disaster the Vulcan will be the most over-seen and over-photographed aircraft in the UK by the end of the summer - it's almost reached that status in a couple of days already!
Nice photos though Nick, especially with the VC10 - very difficult to come-up with an angle on 558 that hasn't been seen before so the formation shot is a gem!
