Hi Downunder & Brian,
Abbeyshrule Air Showns go back at least as far as the late 60's ! Even before they were held at the present airfield, there were several shows at the old Abbeyshrule down the road. Folklore was that a Air Corps Vampire blew down a farm gate during a low pass. Maybe even true !
Ted McGoey at the Rustic Inn is the man for Abbeyshrule airfield history.
Dont remember show at Glenamaddy but do remember helping put up the first wind sock there along with 3 fellow Dubs. Rallye G-ATIW was the aero club mount, later became EI-BCH.
