Quiet skies in the U.K.
From the folks at AirportWatch in the U.K.:
This is an amazing day to be sending out news about airports !
With the volcanic clouds filling the upper atmosphere with an abrasive mixture dangerous to aircraft engines, it seems to be the quietest day in the UK's skies (apart from some helicopters) for many decades, with just about all the UK airspace closed. There have been comments from hundreds of people to say how much they are appreciating the peace, realising just how noisy life usually is, and listening to the unfamiliar sound of birdsong. An unusual day. Lots of good information about it on the BBC website.

Not a trace of contrails in the sky. It has been suggested that when the FAA closed the National Airspace System in the US for three days immediately following 9/11, not only were there no contrails, but there was an anomalous increase in the average diurnal temperature range for that three day period.
The April bulletin is on the website (8 pages):

I hope you find it interesting. Or useful. By the next bulletin there could be a different government, and a different set of challenges and personalities on the aviation scene.
