I fully understand them not testing the procedures fully. I'm currently designing a new type of seatbelt - out of spaghetti. Now, there may be a small possibility that someone might get injured during live tests. So I'm not going to test it properly and instead I’ll use my expensive computer to demonstrate just how safe my new Pasta Safety Harness really is.
The words “Titanic” and “…but there’s not enough life boats Jack!” spring to mind.
