Pilot shortage is all well and good. I'm still waiting for that magic call.
It's the engineering shortage that concerns me. Here's my spin on it:
When you get into an aeroplane to fly somewhere, you either interact with your pilot, or if in a bigger machine, you at least know that there is 2/3 pilots up front.
You accept that they have been trained, and have (usually) earned their position.
How do you know what standard of engineering/cost cutting has gone on under the floor? You can't even see what has been done (or not done as the case may be....)
