KN,
I suppose it is "Just" so long as it is a published policy and is followed through on when said event occurs. After all, fair warning had been given.
That beats the old policy of Secret Handshakes and Management supporting Management even when Management knew Management was wrong.
What's the odds of this particular Crew ever making the same kind of mistake again if they only endure a week long suspension and a Hats On-No Tea interview with the Boss Fellah and being told to go back to Work?
What is more important is everyone else who was not in that Cockpit learning a lesson from what happened. We might laugh at the poor guy's but deep down we should fully understand it could be us next time unless we pay better attention to what we are doing.
