Its not just Icelandic banks that cause grief!

This is a screen shot from an aircraft tracking programme called Plane Plotter. It shows aircraft positions in "real time". The lack of aircraft north of a line from Swansea to Ipswich is not due to a fault in the system, but is a result of a volcanic ash cloud (that resulted from an eruption in Iceland) drifting over much of the country. As a safety precaution all major airports north of this line were closed which has resulted in many cancellations and diversions. Aircraft normally overlfying the UK (between North America and mainland Europe) were rerouted much further south than usual so as to avoid this area and the possible risk of ingestion of the ash.
