Just spoken with Polly Vacher (the Round Britain flyer), who is currently being shown around the tower at Derry (presumably they have the time to do it at the moment!) and is leaving the airport to continue her flight at 10:30am local.
Some wag on BBC Radio Ulster this morning suggested that Ryanair should not cancel their flights from Derry, but simply operate them from Ballykelly... after all (as the caller said) they've done it before!!!
