EVERETT, Washington (AP) — A fuselage section of Boeing Co.'s new 787 jet has passed a series of stress tests that had to be done before the plane can begin flight testing, the company said.
The Chicago-based aircraft maker put a composite fuselage barrel through tests that simulated the most extreme conditions the airplane is expected to experience over its lifetime.
Engineers also subjected the fuselage section to 150 percent of its so-called ''limit load,'' then pushed it to the point of destruction.
Boeing, which assembles its commercial planes in the Seattle area, said the fuselage did not suffer as much damage during that test as engineers had anticipated.

Well it passed the extreme low altitude flyby test a couple of months ago.
Another milestone. I will happy to see this bird fly.
I want to see a 787 barrel roll.
That will be marketing thunder.
The plane passed, but the pilot didn't!
Actually that was a 777, the 787 hasn't flown yet.
I was thinking the same thing! :-D
That was a 777 not a 787 that did the low flyby.
Loop the SOB!!!
The Straight Dope: Is it possible to loop or roll a 747 jet?

“Well it passed the extreme low altitude flyby test a couple of months ago.”
Maybe in your dreams or using Microsoft FlightSimulator.
Structural stress test is essential if not vital before maiden flight.
That answer obviously was not written by anyone with knowledge of flight.
A 1G roll should not be a problem. A loop, on the other hand would really stress the airframe and it’s capabilities. I am skeptical of the author’s knowledge on the subject, but I’m no expert either...
with the computer power we have now it should be able to be simulated with no issue.
FOOTNOTE: has anyone tried a barrel roll of a 747 with flight simulator?
