I was recently through Heathrow and made the point of expressing my disgust at the process that led to this horrific case.
My conclusion is sadly that we are dealing with muppets at that end of the business.
For my younger colleagues who have decades rather than months ahead of them, I profer one piece of advice. If you choose to nurture your young rather than eat them, you will eventually win this dumbing down process that is overtaking our profession.
Failing that...take up yoga and learn to hold your breath from sign in to boarding.
