Earlier quoted context omitted.
Risk has to be put in context. It's one of the biggest risks, where all the risks are fantastically low against number of flights and passenger/miles. All airline risks are lower than driving. I would have said the 787 lithium battery risk was more concerning personally. Or the 737 Max problem.
To be fair, the oft cited “air travel is safer than cars” statistic is on a passenger mileage basis. When you pack an order of magnitude more people at a time going an order of magnitude faster than a cad it looks super safe. If you compare it on an hourly basis it is still safer but not nearly as safe as people would like to think. Especially if you add in small commercial/charter planes
Because of more active drivers and low occupancy cars, I would think from first principles for a constant rate of suicide ideation in the population the risk of death by driver suicide as a side effect is high, and must actually be higher than pilot suicide risk. You are not in the car but the accident affects you. You are driving more often that it's more statistically likely to drive near another driver who deliberately drives dangerously, than the risk of a pilot ending it all.
But if we stop obsessing with the risk of pilot suicide and were just talking overall risk, passenger/miles is the best measure there is. Trains might win.
