Doncaster Robib Hood Galactic Spaceport is situated within some of the busiest open FIR in the country - Gamston,Sandtoft, Netherthorpe are all close by ,Sherburns training area is to the north and a lot of GA/military traffic transit via GAM.
Doncasters IAPs are in open FIR. Listen to Donc App trying to provide a safe RAS with so much unidentified traffic on their screen to get an idea of their workload.
Doncaster are in the process of applying for Class D protection and this will inevitably be approved.
I would urge anyone flying close to Doncaster to make use of their FIS/RIS/RAS and to comply with any ATC requests. A mid-air between a light aeroplane and a civil airliner in open FIR would lead to knee-jerk draconion airspace restrictions.
Flying out of Sherburn I have found the Doncaster controllers(based in Scouseland) extremly helpful and accomodating and I hope that they will continue to be so when they have their Class D airspace.
