It has nothing to do with the RAF sending Pumas/Chinooks to the Leuchars Air Show, the decision rests with JHC.
Airborne Artist, there have been Pumas flying in and out of Benson almost daily for at least the last month and on at least a weekly basis for the past few months.
The RWOETU have been flying since last year and the first bunch of QHI/QHCIs have recently qualified.
