Why is it so high relative to commercial?

Regarding Boeing, let me step back a minute. The background on Safe Flight is relevant here. Leonard Greene, the founder of Safe Flight, had the company itself holding around 120 patents. In the late sixties or seventies, when airliners were crashing in thunderstorms due to wind shear, he developed an algorithm for wind shear detection that could drive a flight director, which could be tied to an autopilot for avoidance. This was a significant safety feature.
