Rocket planes!!!

[collapsing_rain]

First commercial rocket plane to be ready in 2040 or so. A rocket plane is like a rocket but it flies horizontally at super sonic speeds in high altitudes. It takes off and lands with normal aeroplane engines to reduce noise according to the latest prototype

this is not a new idea they used rockets before jets had been invinted< the german nazis i think, but anyways as you can see , as we arent useing them now, it didnt turn out very well and plus jets can already do all of this and with less fuel

I think a nuclear powered jet is a better option. Its probably do-able now
