Airplane Speeds Have Stagnated for 40 Years

What happened to this high level of innovation in air travel? Civil supersonic aviation was banned over the United States in 1973 because of fears that sonic booms would damage buildings and constitute an intolerable nuisance. The outright ban limited the market for the Concorde to transoceanic routes and destroyed incentives for research and development of new supersonic transports. Since 1973, airplane manufacturers have innovated on margins other than speed, and as a result, commercial flight is safer and cheaper than it was 40 years ago. But commercial flight isn’t any faster—in fact, today’s flights travel at less than half the Concorde’s speed. If we want to restore mid-century levels of aviation innovation and break the sound barrier again, we must first break regulatory barriers. The FAA should lift its ban on civil supersonic flight. Legitimate concerns about supersonic flight can be handled by specific policies that address concerns directly, such as a clear standard from the FAA for acceptable noise levels. It would be a shame to suffer another four decades of aviation stagnation. Mercatus Center Think Tank at George Mason University- Airplane Speeds Have Stagnated for 40 Years | Mercatus |
Perhaps it is that we found the limit 40 years ago. Drag rise approaching sonic will kill fuel burn. I don't see it getting faster without a breakthrough in propulsion. There has been some development in material recently, but not enough to gain the efficiency that will be required to deal with increase in drag.

Passenger boats are also no faster than they were 50 years ago, and anyone who has ridden one of those loud, rough, turbine-powered craft (for example, on the Rhine River), will understand why. :rolleyes:

The Space Plane is the next big thing. 1 hour to get into orbit altitudes, 1 hour to come down. So, JFK-DCA is 2 hours, JFK-HKG is 2 hours.
I assume that the first commercial space planes will only seat about 20 people, and it will cost a lot. |
It would be nice to see them relax 1970's regulations, the industry has changed a bit since then. |
