Problem with SST is its a great idea in theory,but we have a little problem called shockwaves.
To cut a long story short,a new aerodynamic method has got to be found / developed to reduce the intenity of the sonic boom,which has a reputation of smashing windows,especially greenhouses,scaring cows (in cornwall they go bonkers apparently...) and causing disruption which people won`t tolerate.
Once thats been pioneered,then a aircraft could go overland at supersonic speed,thats when the SST age will really happen.
