C-17 Globemaster III project

Hi guys, im a member of the ATC and doing my DofE award and i picked aircraft recognition as my Skill. I've been asked to produce a project of an aircraft in service in the Royal Air Force. Of course me being a lover of the beast i picked the C-17. Does anyone know where i would be able to get any technical information about the C-17 or if anyone here knows any information that could be useful please post below...
Thanks guys
