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.
Ryan was a pilot for Ryanair until 2002.
This is definitely incorrect, as he resigned from being a pilot in 1996. The system may not have understood the wording in the context.
