US Airways Flight 1549 (Sully)

Mentioned only as the more famous later analog to the Sioux City glide landing.

All of a sudden, the pilot had to do a glide into Sioux City, Iowa, airport. He did it successfully — sort of like the guy who landed the US Airways airplane on the Hudson River. They made a movie out of that. Sioux City, Iowa was before. It turns out it was a titanium nitride inclusion from the casting process that caused a fatigue crack in the titanium disc. Brian has a lot of stories about this, including how it caused General Electric to redo a lot of their quality control metrics. You have a serious problem when you get to five and six sigma. How do you fix the problem and get to a higher level of reliability?

Tom's review of the *Sully* movie (2016). NTSB portrayal disputed. Hudson River landing after dual-engine bird strike at 2,800 feet; 155 survivors. Used as setup for bird-strike engine certification story.

Strength versus temperature. This came up in the last two weeks. I missed a day last week — had to be down at an inspection of an aircraft — and one guy told a story about the problem of bird strikes. So Monday night my wife wanted to go see Sully, the movie Sully, because my daughter had seen it and said it was worth seeing. It's not a bad movie. It has nothing to do with reality. The NTSB was made a bad guy by Clint Eastwood — they were not a bad guy in the real world. But they made him a bad guy. Clint Eastwood had to sell tickets. It's an entertaining movie — think of it as fiction based on fact. The guy really did land a plane in the Hudson River. That's about as far as the fact goes. It was a bird strike, he lost both engines at 2,800 feet, and he had to land in the Hudson River. He was successful — 155 people all survived.
