Are they at it again ?

Ryanair in the news today - "A RYANAIR pilot and the Irish Aviation Authority are at loggerheads over claims that a landing at Cork Airport had to be aborted because of an obstruction on the runway. The pilot of the Ryanair flight, the 3.45pm from East Midlands on Sunday, told passengers on board the Boeing aircraft that an “unscheduled” plane on the runway prevented him from landing. The pilot initiated a “go-around”, which involved circling and approaching again. The plane landed safely a short time later.... ... However, a spokesman for Cork Airport said there was no obstruction at the point of landing and the reason the pilot had to initiate a “go-around” was because it had been advised it did not have permission to land. " So is it a case of Rynair getting their excuses in first or is it another manifestation of these problems referenced here .
