> DoD has estimated that all training and operational operations over the 50-year life of the program (assuming a 30-year life for each aircraft) will be $1 trillion, making the cost to buy and operate the F-35 at least $1.4 trillion.

A little bit of clickbait there. $1.4 trillion projected over 50 years. Don't get me wrong, I'm not saying it's a great fighter. But we haven't spent $1.4 trillion on it (yet).
