Gaseous: just because these pubs have landing sites doesn't give the pilot carte blanche to shoot an apporoach
Rule 5(d): blah blah blah...."conducted without hazard to persons or property on the surface".
Is the critical bit. You can't land at a pub where you intend to touch down 20 yds from the public, just because it's a legal landing site??????
YOU the pilot have to take every measure to minimise damage to persons vehicles vessels and structures....OR ELSE accept the consequences.
