COVINGTON, Ga. (AP) — Two people were killed when a single-engine plane crashed shortly after takeoff late Saturday from a small airport east of Atlanta, authorities said
Police said responding officers found the aircraft and the two victims in woods just north of the runway in Newton County, about 35 miles (55 kilometers) east of downtown Atlanta.
The crash is being investigated by the FAA and the National Transportation Safety Board
24.83 fatalities in 2019 and 25.95 in 2018 per 100 million miles ridden on motorcycle according to the source of the other article: https://crashstats.nhtsa.dot.gov/Api/Public/ViewPublication/812979.pdf
If we take the value for personal flights:
I’m going to assume 125 mph as I’m skeptical of your 145 mph figure.
= 21.1 fatal per 125 million miles
= 16.88 fatal per 100 million miles of personal flights
I’d basically conclude that personal flights and motorbike are in the same ballpark whether you’re looking at hours or miles.
