The downside button is not meant as a disagree button.

Anyway, there was likely nothing Boeing could do at the early design stage to make up for poor choices on the engine manufacturers part except a higher degree of scrutiny with regards to the actual manufacturing facility and essentially double checking all of RR's work.

Considering they are questionable at certifying their own work, I'd not necessarily look to burden them with being an engine manufacturer on top of an airframe one. As irritating to me as that is that quality departments typically don't integrate vertically or even share that type of info to enable that type of analysis.

It was a problem with the engine, not the airframe. The 787 ships with Rolls-Royce and GE engines - the GE equipped ones are fine. Boeing manufactures the planes, and then works with engine manufacturers to offer various options for powering them. The airlines choose which engines they'd like to install on their aircraft.

GE, for all of its faults as a corporation (the stock price is what, $9-something now?), makes very good jet engines.

What does this have to do with Boeing? Engine was from Rolls-Royce. The customer decides what engines they want to install on the plane.
