All flights from UK airports were cancelled indefinitely after Ryanair chief executive Michael O'Leary erupted in the early hours of the morning, sending clouds of expletives and obscenities miles up into the air.
O'Leary, who has become increasingly frustrated in recent years after clashing with the Civil Aviation Authority over carbon emissions and health and safety issues, finally exploded at the decision by the CAA to close seven UK airports because of drifting ash from the Icelandic volcano.
The chief exec became "positively apoplectic with rage" when he heard the news at his home in County Westmeath. Locals report that O'Leary then launched into a 20 minute rant that "caused the sky to darken and the earth to tremble".
The UK emergency response committee Cobra, chaired by Prime Minister David Cameron, decided to close down all UK airports immediately.
The ban is not expected to be lifted until Cobra receive written confirmation that Ryanair's chief has been sedated.
