Icelandic volcano: are you enjoying the clear skies?

Thousands of planes across Europe have been grounded for a second day after Iceland's Eyjafjallajokull volcano erupted on Wednesday. Air traffic control body Nats extended its restrictions on UK airspace amid fears the volcanic ash could cause engine failures. Not since the second world war has Britain seen such an extensive flight ban. Holiday plans may be in ashes with thousands of confused passengers grounded at airports but, for many, the lack of air travel has meant a brief respite from the daily aircraft noise . Have you noticed the calm since flights were grounded?
