On my first solo out of the circuit I closed Dublin Airport!
Blocked approach to both runways.
Was on Weston's channel.
Oops!
When Weston eventually told me that Dublin were looking for me, Dublin asked to confirm that I was unsure of my position. To which I replied "Oh Yeah, Oh Yeah". "Would you like to land here?", "Oh No,oh no"
A great thank you to ATC in Dublin and the guy who put me straight back into the cockpit to repeat the exercise.
