The F1 world is once again keeping a nervous eye on an ash cloud produced by an Icelandic volcano eruption.
Almost exactly a year ago, the sport's travelling circus ground to a halt when airports closed due to an unpronounceable Icelandic volcano.
On Saturday, another volcano - Grimsvotn - erupted in Iceland and the dangerous ash cloud is now en route to the UK, according to the Bloomberg news agency.
Some flights in the UK and other parts of Europe have already been affected, while other countries imposed rules about the air density of ash that would affect the safe operation of planes.
"The low-level winds are blowing strongly towards the UK," a spokesman for the Icelandic Meteorological Office is quoted as saying by AFP.
A spokeswoman for the European transport commissioner added: "There is at the moment a possibility of volcanic ash affecting the European airspace."
