Menzies Strikes Again!
Thus far, Menzies' damage in Seattle has been confined to screwing up the operation, making the company lose important seafood cargo contracts, "tagging" the baggage holds with graffiti, getting into a gang fight on the ramp, and a few dented airplanes. But now they've finally managed to screw up bad enough to put passengers at risk.
You can read the whole story at this link, but here's what basically happened. A Menzies ramper backed a bag loader into an MD80 but didn't tell anyone. The MD80 took off for Burbank and lost pressurization while climbing through FL260, forcing a return to SEA. After landing, a 12" x 6" gash was found in the lower fuselage. Upon questioning, the ramper fessed up and claimed that he didn't even see a dent after he hit the airplane. The company got a damaged airplane, negative publicity, and unwanted attention from the FAA - but hey, Menzies is saving them money!
