We analyze why by comparing it with its more successful sister, the 787-9. The 787-8 and -9 were conceived together, with the -8 as the first birth to be quickly followed by a longer version, the 787-9.
With the troubles of the program, it took three years before the longer 787 was ready. By then it was in many ways a different aircraft than the 787-8.
The 787-8, as the first aircraft in the 787 Dreamliner series had to crack the brunt of the program's many problems.
As a result, it ended up with first try solutions in many areas where the latter 787-9 could gain from the experience and use improved designs.
We analyze what this means for the economy for the 787-8, both from an operational and manufacturing standpoint.
