You know how if you google an N number the FAA site comes up with information on the registration?  For example, if you google N25673, you will find a page stating that it is a Douglas DC-3A owned by the Texas Aviation Hall of Fame (or maybe its under Lone Star Flight Museum, I don't remember)

Well, is there something like this for UK aircraft? (G-????).  Or even Canadian?  (C-????)

Had a quick search and got this.

G-INFO is the UK site. Normally I find typing any registration into google give a fairly decent answer, often from A-net...
