The RAF use a network called the Logistic Information Technology System, otherwise known as LITS (or Lost In Time and Space) for ac engineering and asset management. It's not quite up to scanning documents but (aircrew: commence uncontrollable laughter) it is quite good at locating items by component number and calculating rolled-up remaining life on significant components or assemblies, including entire ac. It's based on a Sth African Defence Force system called OSIS and coded by a bunch of geekoids at IBM UK in Stevenage.
Sounds like you might have one over us there. How long did it take to do 50 ac?
