Texas was able to become a leader in the aerospace industry because of NASAs headquarters which is located in Houston (aka my hometown :D )
Not sure what the options are but there was a huge wave of immigration during that era.
Starting in the mid 1800s, hoards of people traveled to the west out of desire to find land, and there was offered land under the Homestead Act. This was a series of acts that was passed in the year 1862 and it offered 160 acres of land to the settlers. I hope the answer helps you.
