How A Small Irish Airline Conquered Europe, sitting on the fiction shelves of a Dublin Airport bookshop. Any number of suspects would like to see Siobhan Creaton's book categorised as fiction, given the many rows Michael O'Leary has had with union leaders, Aer Lingus, Aer Rianta and the European Commission. But given that the book (fairly) credits O'Leary with Ryanair's ultimate success, there's also any number of people loyal to Ryanair founders, Tony Ryan and Christy Ryan, who may feel the pair have been overshadowed by their publicity-generating chief executive.
