"Welder John Taylor was given a 15-month suspended prison sentence for having gone against industry norms and used titanium to forge the piece that dropped off the plane."

Titanium is very hard to weld properly. And I'm sure it is also very hard to constantly scan runways for small items on a busy airport.

Since a company IS responsible for an employee's carelessness, I guess that verdict was about as close to 'fair' as possible.
