I will often make a dash towards a seat in 1A/B/C when flying FR... means a quick exit at the other end. I've often watched families boarding and pondered the implications of the huge gap between the aircraft doorway and the air stairs.
As an architect, if I design a building that meets current UK building regulations, no ballustrading to stairs, landings, balconies etc must have openings wider than the approximate diameter of a baby's head. Yes, I'd agree it's elf'n'safety'gorn'mad, but it does go to show the different circumstances we operate under. Ryanair depend on their airstairs for keeping airport costs down and turnarounds nice and quick. One more errant toddler and this whole issue could turn round and bite FR very deeply in the derriére...
