This would immediately take plane travel from “Bullitt” to something a lot closer to what we should have in the 21st century.
But I am curious as to how this would work for passengers. One complaint about the Concorde (which I sadly never had the chance to ride on before it was retired in 2003) was that it was pretty uncomfortable to be on.
That said, if it can cut a 20 hour trip to 4 hours (London -> Sydney), I think I’d take it. What would San Francisco to New York be? An hour? Would the thing even be able to get to top speed in that time?
Also note: this is meant for business jets first (in 2020). It wouldn’t come to commercial airlines until sometime closer to 2030 (if at all). Still, this would absolutely change the state of travel.
and we’ll spend longer in the airports checking in, passing security and immigration than we’ll spend in the air….
