I’ve seen these aircraft flying about before in Galway, but this one  seems to flying a little bit close to the shore both metaphorically as well as literally earlier this month when the pilot did a low pass along the shore in Salthill. According to the aviation rules outlined on the IPPHA website (Irish Powered Paragliding and Hanggliding Association) :-

No flight may be made at any height over: a. Any town, City or built-up area. b. Any area of commercial, residential or recreational use. c. Any open air assembly of persons, whether gathered in connection with an event of public entertainment or otherwise.
