To be fair Sherburn is probably the most ideal place to run the course from the point of view of proximity to leeds and ability to handle the volume. LBA was always the initial intended location prior to Jet2 starting up but is just not feasible for the volume or cost.
The course has actually been run from Sherburn before in its very first year, but the local pilots did get quite frustrated with the incredibly busy circuit all week long. Although might be more acceptable if it is using the Sherburn aircraft now bringing more money in for the club rather than additional aircraft.
