Isn't that an oxymoron?
The F-35 seems to my non-expert eye to have been poorly conceived but creating a more versatile aircraft instead of a bunch of more specialized ones is not inherently a stupid idea.
China may get to the mass-produced stage, but that's stil debatable, since they have issues with their engines.
And still I'd say - yes, it's better.
And for a military aircraft I guess the answer will always be 'really good'.
Of course the design of the APC in your clip is only the opening of the disaster. Once it got to testing before the actual acquisition things got even more ridiculous to the point that I think people should have clearly been prosecuted for reason. But as Boyd said: You can either do something or be someone.
Did no technology programmes in the 60s fail or have limited success? All of them were complete triumphs?
