In 1986 he became the head of London European Airways, a business in which Ryanair had bought an 85% stake. This position, however, quickly disappeared as the carrier became Ryanair UK and was then merged entirely with Ryanair. Over the next decade, Cathal worked both on the executive board of the airline and as a pilot, although he resigned from the latter by 1996. He remained with Ryanair until leaving the board 2002, by which time he was a multi-millionaire due to the success of the airline.
Cathal returned to Ryanair as a pilot after he had retired.
The statement says he resigned as a pilot in 1996 and but does not say that he never returned after his resignation so it is neither definitely correct nor definitely incorrect that he came back as a pilot.
