The F-35 program also comes to mind. Or the high speed train effort in California coming in at 10x the price per mile compared to European equivalents..
The F-35 is going to join the long list of fighters that will be pulled from service as quickly as possible.
It might continue to fly in the Air National Guard, and in countries that don't have the means to renew their fleet, where it will have served its purpose: being so costly that it starved any possible competition.
Anyhow, being able to fail is a good thing, believe it or not.
