Funnily enough, I caught that driving out of Rhoose on the way to work. Considering I did my first solo at St Athan, it took me a concerningly long time to realise what on Earth a 747 was doing flying almost perpendicular to the Cardiff threshold.Fenlander wrote: ↑Mon Nov 25, 2019 11:24How's this for coincidence, as I was reading this post a message just flashed up on the notifications on my phone to say a Boeing 747 has just taken off from Cardiff heading to St Athan, a distance of 4 miles as the crow flies (not being a crow of course it took off heading south east, did a 180 short of Flat Holm Island and came in to land heading south west at St Athan. It got as high as 3,375ft!). That must be a hideous pollutants/mile set of figures.ais523 wrote: ↑Fri Nov 22, 2019 17:02That message may well be safety critical. The reason that avoiding accidents has safety importance is that it reduces the number of injuries and deaths. Avoiding deaths due to air pollution is just as important when it comes to reducing injuries and deaths; crashes aren't the only way to kill someone. So if overspeeding is causing deaths as a consequence of pollution, a sign warning people against it may well save lives, at least if people obey it.
That said, it's unlikely that aircraft will be polluting anymore. It'll be on its way to Ecube to have its guts ripped out and sold to a hundred different MROs. Funnily enough I used to work for them as well.
