I saw a short TV report a few weeks ago about airbags in aircraft.
Development for such system is already done - but the system looks
quite different to that installed in cars: The airbags have to be
blown up "manually" by a central switch in the cockpit in case of an
emergency. So there will be no time span of milliseconds but rather
minutes. And the airbags stay blown up.
I don't know if this makes any sense ?!
