I have a question about this article about "The Fifty", Alcoa's 50,000 ton forging press.
The second paragraph states that this machine broke down 3 years ago, and only returned to service earlier this year, implying a 3-year outage.
A little later, the article says "Every manned U.S. military aircraft now flying uses parts forged by the Fifty. So does every commercial aircraft made by Airbus and Boeing."
So my question is: what parts did they make with this press, and how were they able to ride through 3 years of downtime? Did they really have 3 years' worth of inventory when the thing broke down?
