So the wing set in question would have completed as many cycles as any aircraft achieves in service...then failed at 147%
Are you sure about this??
nope, he is not shure (or he might be, but he is wrong)
The wings completing more than 2 simulated lives is still beeing tested in
Dresden. The one in Toulouse was never tested in fatigue.
And for the Comet, it was the other way round. The test fuselage (section) used for fatigue testing was used for static tests before, "coldworking" all the high stressed areas. This led to a high fatigue life of the specimen, which was misjudged at that time to the best knowledge of engineers and authorities.
