Reminds me that the first U.S. ship to ship night naval battles with the Japanese in WWII were tragic (for the U.S.) 'cause the American super-fancy new-tech Mark 14 torpedoes hadn't been properly tested; that would have been "too expensive." So they were just made and deployed - and since defective, didn't trigger. https://en.wikipedia.org/wiki/Mark_14_torpedo https://en.wikipedia.org/wiki/Mark_14_torpedo So "this engineering mistake" indeed has to be made ad nauseum, it would seem. As Einstein said, only space and human stupidity are infinite.
