At least the 787 passed the load test the first time.
Bend Not Break: Boeing 787 Passes Wing Load Test - CBS News
Unlike the a380 like I had mentioned above and referenced here.
Airbus A380 test wing breaks just below ultimate load target
What was interesting is Boeing traditionally pushes the first one until it pops, mentioned in the first article b777/1994 at 154%. Sounds like they got what they wanted out of the 787 and called it a night. I would like to know what the B787 wing is actually capable of.
