The Mercury aircraft were made here in St. Louis.
My brother-in-law was one of the individuals who worked on the wiring for the capsules at McDonnel Aircraft, and even though we do not get along, he is a genius, as are all the folks who worked on the project. (I know, I know, it's hard to believe that someone doesn't like little ole me!)
NASA actually ordered 20 spacecraft from McDonnell Aircraft Co., St. Louis, Missouri. Five of the twenty were not flown. Spacecraft #3 and #4 were destroyed during unmanned test flights,#11 sank and was recovered from the bottom of the Atlantic Ocean 38 years later. Some spacecraft had changes made after initial production (refurbished after launch abort, modified for longer missions) and some were given a letter designation after their number, 2B, 15B. And some were even modified twice- spacecraft 15 became 15A and then 15B.
Space a great Frontier!
