Hi Boe 777. Re your comment “…glitches notwithstanding I am sure they would have considered all pros and cons before assembling the aircraft……”
it does not look like it to me, and I doubt that it looks like that to anyone. The main point is surely not that it is late, or how it’s lateness compares with the development of other aircraft past or present; the main point is surely why it is late. In short, they cannot get the wings to stick on properly without damaging the rest of the aircraft. This is a problem of a different order of magnitude involving the main structure of the aircraft, as can be seen from this video KIRO 7 Eyewitness News Video, Seattle, Western Washington
It does not look like it is going to fly anytime soon. It is a sitting duck, and no one needs to waste pellets on that.
