Woke up to a clear blue sky yesterday.....lots of aircraft chemtrails...two hours later....the sky was 199% grey......not  natural.....i live in ireland.....we do not have an air force so

You do live under a major trans Atlantic and UK civil  air route though , used by much of the air traffic entering and leaving  UK  airspace 1000s of them, as well as the domestic flights .   Shanwick control in Ireland an Prestwick actually handles this traffic .
If you look at  Flightradar24.com  you see aircraft plotted in real time and info like their height , speed and destination and the airline. There's another similar site which  shows some military ones too . A pair of binoculars confirms the information you see on screen as you can see the airline company colours .

I've had my eyes opened on many other things over the last few years  and It's very likely that   weather manipulation has been going on or been tried for years , but  I'm very skeptical of "chem trails "  , simply because  I've been interested in weather and aircraft  for a long time and think the more mundane explanations for the way vapour trails behave on certain days are the most likely .
