Something else to consider about CT's immanent production debut is how this vehicle will have front and rear castings. Meaning, they will need to have two of the large IDRA machines running to reach production.
As far as I know, there is only one of these being assembled on site currently, and there has been no perforation in the roof for the aluminum smelter for either of these Gigapresses per Joe Tegtmeyer's drone videos.
Usually, there is some buzz when IDRA ships another press, and again when the press is delivered to GigaTx. Any timeline for CT production should take into account such evidence as indication of when both presses have been installed and are operational. Other things to look for would be CT casting test articles in the recycle pile on the North side of the building.
