In United States airspace, the average number of commercial aircraft in the sky on an average morning is 4000. There are another 16,000 planes on the ground. Aerospace company Rockwell-Collins developed what it calls a “digital parachute,” a panic-button technology that will land any plane in a pinch at the closest airport, no matter what the weather or geography, and without the help of a pilot. The technology could be applied where a pilot is no longer capable of flying the plane, or is panicked and confused about what to do in an emergency. Assume the cost of retrofitting 20,000 commercial airplanes is $55,000 each and the plane stays in service for 15 years. The technology could save an estimated average of 40 lives per year; the value of a human life is estimated at
