So he failed his CPL twice, IR 3 times, had control taken from him on 9 landings out of 28 that he'd flown on the Airbus...
Obviously got "the right stuff" that airlines looks for these days, which has nothing to do with flying skill and prowess, but passing fancy selection tests which bear little relevance to flying, and the ability to pay for 150 hours of flying an Airbus. The sort of person the military would probably "bin", but who is able to keep paying in the civil world, with the end result being a grounded aeroplane.
Fantastic.
