i'm not defending anything - just trying to provide a bit of balance to the above.
Hendon is a nicer, more modern place now. Like it or not, they have to cater for the future generations - if that means having more cafe space for families and kids play areas, then so be it - where is the next generation of future RAF personnel going to get its' inspiration from? I do sincerely hope you're a parent of young children, so that you can understand why there are places for them to burn off a little energy and to sit down and feed them.
There are 3 more huge buildings that house aircraft (if you include Hangar 2) from all eras, so complaining about the Sunderland really is a moot point, especially when the initial complaint was about aircraft making way for cafes when the whole site is packed with aircraft.
