I am amazed at how many great ideas are coming out of people who know nothing about planes.
They insist things should be different, yet they don't cough up the money, or actually design stuff. They don't make prioritization decisions like...spend billion dollars on new gadgets when it might be better to spend money on avoiding the situation in the first place.
Most planes are pretty good. Stuff happens. IF you want to prevent all accidents are you prepared to pay 4 times current ticket prices to get even half a percent safer travel?
