This one is new. They just removed Engineering pre-flight safety checks on the ground.
Yes, makes perfect sense. Don't worry about picking up defects on the ramp, or having skilled people there who can pick it up, wait til cruising altitude and 900 km'ph....
Oops I forgot, NG aircraft, they don't or won't break anymore. How silly of me.
The main way safety related defects will now be identified is the air.
Especially good if you have problem with hydraulics, engine output of a tear in the fueselage wear a rampie has hit the bird with a belt loader. Much better to find out at 37 000 feet.
