There are most definitely restrictions around airports for drones.

It says
"Class: FRZ Active H24. Unmanned aircraft flight not permitted unless permission has been granted by the relevant Air Traffic Service unit or aerodrome operator. For contact details see AIP, Part 3 - Aerodromes, Section AD 2.2"
There is no way they will grant permission for a consumer drone. Not that it would cause issues at the height it was being flown at, but bugs me more for privacy reasons.
