of travel between them below about 500 miles of distance where the hyperloop would be useful. it is a special case. once the distances get long, then the amount of time an aircraft takes to ascent and land, which is mostly what it does on the 500 mile trip, that percentage declines and it is better to use aircraft. >> reporter: we dream about moving comfortably from place to place in a blink of an eye. that is the dream of the hyperloop. >> what is the hyperloop? >> it is very similar to an airplane on high altitudes. you have a low pressure environment. and because of the low pressure, it doesn't encounter resistance. >> reporter: this has been around for more than a century. in 2013, elon musk drafted blueprints and put the challenge of building it to the engineering community. enter ucla.
