"I know lives may be at stake" What lives are at stake? An enhanced black box won't prevent accidents, and, with very few exceptions, it won't help us find out the cause of accidents. I think your take on the "cost-benefit" analysis made the most sense. Your 1 in 17 million scenario is interesting - how many times per flight is that scenario evaluated, or is that per flight? If per flight, and suppose we have about 20,000 Boeing flights a day, then we would have a Boeing explosion every 3 years. (Adjust the numbers based on how many Boeing flights there are) - I would say it's worthwhile making the change there.
