Not just Boeing

The crew at the airport didn't carefully check the Airbus:

A New York-bound Virgin Atlantic flight was canceled just moments before takeoff last week when an alarmed passenger said he spotted several screws missing from the plane’s wing.

It was an independent wing. It wants to soar by itself! It needs no oppressive screws!

Seriously, it begs the question: what the hell is the maintenance crew doing? If such a visible problem was ignored, then what other structural issues in the planes are creeping up?
