3000 iPads * $800 per iPad = $240k cost of plane itself + cost of all the human lives on it = many millions, or "priceless", right? seems cheap in comparison.

3000 iPads * $800 per iPad = $240k cost of plane itself + cost of all the human lives on it = many millions, or "priceless", right? seems cheap in comparison. plus they don't need to perform this test on every plane before every single flight. only once or a few times, per model permutation. If you spread the testing cost across all the operational instances where they'd be de-risked, I bet it would be pennies per flight, at most.
