Pneumatic technology is now presented as something new and futuristic, when it has existed since at least the 1800s. There is copious evidence that old cities in Germany, France, England and the US had extensive and elaborate pneumatic networks for delivering mail – and also for transporting people. When building crews dig up ground in the major cities in these nations, they are actually doing excavation and repair, not construction. See for yourself. This presentation also includes some interesting information on the old Ohio Air Lines. Is it possible our recent ancestors had more advanced technology than we do now?
