Ryanair lands at wrong airport

Just heard a bit about it on BBC Newsline (Northern Ireland)
It was meant to fly to Londonderry/Derry but accidently landed at the nearby army base airstrip.
Landing was normal.
I dont know if its still there or if it went back to Liverpool or Derry.

I would love to have seen it!
After all the army base is behind my house!

Sorry thats all the info i have
