Here is a quote from the company's website that shows how this is different from some other efforts. (Lawless is Chairman / CEO.) Their assumption is that the regional population will double in the next 20 years and short-haul air and highway will not be a viable option.
"We will not structure this company in any way that will come back and be a burden to the state of Texas," says Lawless. "That is the risk that we take as a privately-funded, privately-owned and operated company." That risk is outweighed by the advantages of staying private, he says. "It just gives you the flexibility to execute the project on schedule, probably with a lot more freedom of action than you would have if it were a government project."
