Imagine flying at more than twice the speed of sound. At that speed, a London to New York flight lasts under 3.5 hours. And the last time that happened was in 2003, just before the supersonic Concorde ceased operating. More than a decade later, there are conversations on whether the supersonic culture can be revived. There are arguments for both sides and the latest is news about the talent at NASA working on making commercial supersonic flight eco-friendly.

Unless you have access to a F-22 fighter jet, you probably haven’t been able to fly faster than the speed of sound since the last Concorde flight in 2003. NASA wants to change this. The agency said that it is spending over $6 million to fund research into cheaper and greener supersonic travel. This isn’t NASA’s first attempt to bring back supersonic travel. It has been (literally) pushing the boundaries of flight for years. NASA’s predecessor was involved in building the first supersonic plane in 1946, and the agency has been working on concepts since 2006 with companies like Lockheed-Martin and Boeing that may one day lead to a new generation of planes that get you places very quickly.

This includes taking a look at increasing fuel efficiency, minimizing damage to the ozone layer, making supersonic travel quieter, and at economic viability. Read more.
