Mercury Retrograde strikes...

All UK airspace has been cleared of aircraft due to Iceland's volcanic ash cloud. See: Icelandic volcanic ash alert grounds UK flights.

Guess when the retrograde is? April 17th to May 11th.

What's a Mercury retrograde? From Astrology on the Web:

Mercury retrograde gives rise to personal misunderstandings; flawed, disrupted, or delayed communications, negotiations and trade; glitches and breakdowns with phones, computers, cars, buses, and trains. And all of these problems usually arise because some crucial piece of information, or component, has gone astray or awry.

Here's hoping the next five weeks will go OK..
