An incorrect bolt sequence? Never thought I'd hear THAT one. If I gave you a $100 bill, would you complain because it was wrinkled?
Wrinkled? I would not mind.
If it had "THE UMITED STATES OF AMERICA" printed on it, I would mind.
If it had a picture of Washington instead of Franklin, I would definitely mind.
Perhaps in the case of an aircraft, it isn't functionally different, but it IS a recognition feature.
