“This is what “vertical Integration” gets you in a world of supply chain issues. Sling Aircraft produces almost everything for their line of aircraft in-house. From building their own spars, to welding up motor mounts—all the way to doing their own upholstery and paint—they try hard to be their own supplier.
Their metal-cutting and -punching facilities produce their own sheet metal parts from a huge supply of raw stock on hand, and their composites shop takes the designs from their in-house engineering staff, produces prototype plugs, molds and then all the finished parts. I think that if they could run a cattle ranch to produce their own leather, they’d look into it! (Might provide great meals for their staff of nearly 350 workers as a bonus).”
