yet we don't seem to be worried that a computer handles deployment of the airbags and other pyrotechnic safety devices (seat belt tighteners etc) automatically in our cars do we? Haven't heard many instances of airbags going off in any other circumstance than a severe impact in a car - why does the automatic deployment of a different sort of safety device (seat) worry others? It's not as though the pilot can respond quickly enough to save himself with a manual response.
