The gent in question I never had the pleasure of flying with in my time at Flybe, but by all accounts he was a more than competent operator. In the end in this incident he also proved his competency.
I fly with guys now who I personally believe are less than competent handlers with two arms let alone one so where is the sanction there? Unfortunately in this industry you just have to meet a minimum standard so they get away with it.
Unfortunately people love to jump on a bandwagon and, even though the situation was recovered satisfactorily, they want their pound of flesh if someone inhabits a space outside of their personal comfort zone.
