"The United States has spent over $320 billion so far to develop and acquire more than 2,400 fighter jets, according to the GAO report.

Dr. Michael Gilmore, the director of Operational Test and Evaluation at the Department of Defense until 2017, also provided a fairly searing depiction of the F-35 program in his FY 2015 Annual Report. He wrote that it would be problematic to make any commitment to a block purchase of the F-35 before November 2021 because of the technical challenges the program faced, but he did not identify fuel tubes as a specific issue."

"While flying by commercial passenger jet was fatality-free globally, the industry did suffer minimal losses. By one count, from the Aviation Safety Network, there were ten accidents involving commercial passenger or cargo airplanes, claiming 44 lives in 2017. (That organization focuses on crashes involving commercial planes, cargo or passenger, meant to carry 14 or more people; it didn’t include the 35 lives lost on the ground during a cargo plane accident in Kyrgyzstan.) By another count, from a Dutch firm called To70, 14 people were killed in aviation accidents in 2017. They focused just on commercial passenger planes heavier than 12,566 pounds at takeoff.

And it’s been a record-breaking 400-plus days since the last commercial passenger jet crash anywhere in the world, according to the Aviation Safety Network’s CEO, Harro Ranter."
