I don't see what intellectual property they have. They use ProPilot manuals for groundschool. Perhaps the flying training manuals / approvals etc ?
Any aviation company has a lot of material which took much took much expensive time to put together.
Think of the time it takes to put together a FOB, manuals for any AOC operations, student handbook, company aircraft manuals and checklists, company W&CG sheets, staff handbook, student record sheets... - it all adds up and if you can take all of that from somewhere else and implement it within minimal modification then a great deal of time, and thus money, can be saved.
Given that £34k is maybe half a man-year of total employment costs of a middle-ranking aviation grown-up, this may be fairly cheap.
