To underline this, here's what happens when something goes wrong with an ejector seat: http://www.bbc.co.uk/news/uk-england-lincolnshire-37475298 http://www.bbc.co.uk/news/uk-england-lincolnshire-37475298 We probably won't ever know how many people died as a direct result of the Hawaii BMD mis-alert, but I'd be surprised if the number was non-zero (think in terms of car crashes, stress-aggravated cerebrovascular accidents, and so on). Similarly, consider the warning signage deployed around high tension electrical substations, and the consequences of ignoring it or failing to understand its significance. The point is, in these types of situation bad design can kill, and we need to design accordingly and unambiguously.

>but I'd be surprised if the number was non-zero (think in terms of car crashes, stress-aggravated cerebrovascular accidents, and so on). I'm assuming you meant you'd be surprised if that number was zero. It's awfully hard to, in good faith, directly associate a message with a death. I mean if you wanted to make it seem bigger than it was, you could associate any crash or heart related death that happened in that 38 minute (?) period as directly a result of the warning, but I don't think that would be in good faith.

  It shouldn't be hard to check if there's a spike in mortality above the median background around the period of the test. Statistical significance will depend on the size of the spike.

    Ya, but like you said, it would have to be a significant spike, particularly for a 38 minute window. I haven't heard anything reported.

That guy's death was apparently complicated by a chain of failures: user error with the safety pin, user error with the firing handle, maintenance/construction error with some bolt, and several aspects of the M/B design that allowed all failures to happen at once. Overall, those seats have saved some 7500 pilots (search for the tie club) and maybe killed a few: similar odds and debate to airbag deployments. ref https://en.wikipedia.org/wiki/Death_of_Sean_Cunningham_(pilot) https://en.wikipedia.org/wiki/Death_of_Sean_Cunningham_(pilo...
