Yes, it is true... but.... as always with Ryanair... things are not always what they seem. Leo the comical has got it right as regards the Ryanair position. Ryanair are not taking them on directly... there is an intermediary involved.
Expect lots of "smoke and mirrors" over the exact nature of the deal. But the essentials are that Ryanair are short of pilots and enjoy a poor reputation in the industry. They are getting around this problem.
When they are no longer short of pilots they will take back what they have given to solve the short term problem. There will then be the usual fuss....
