NEW: President Trump has signed an executive order to scrap regulations that ban supersonic commercial air travel. The supersonic flight regulation was imposed in 1973 due to noise concerns. Trump's order "seeks to revolutionize supersonic aviation in the United States" by letting aircraft fly faster than the speed of sound. "The US used to be the global leader in this technology, but stifling regulations have grounded progress for generations," said director of the WH Office of Science and Technology Policy, Michael Kratsios. "The reality is that Americans should be able to fly from New York to LA in under four hours." More from the White House: - This Order removes regulatory barriers so that U.S. companies can dominate supersonic flight once again. - The Order directs the FAA to repeal the prohibition on overland supersonic flight, establish an interim noise-based certification standard, and repeal other regulations that hinder supersonic flight. - The Order instructs the FAA Administrator to establish a standard for supersonic aircraft noise certification that considers community acceptability, economic reasonableness, and technological feasibility. - The Order advances the coordination of supersonic research, development, test and evaluation efforts through the National Science and Technology Council with leadership from the Office of Science and Technology Policy. - It promotes international engagement through the FAA and other agencies to align global supersonic flight regulations and secure bilateral agreements for international operations. The following video is a collaboration between Boom Supersonic and United Airlines, showing what the future could look like with supersonic flights.

Want to reduce housing costs? Build more homes & cut the red tape that stops us from doing it. Want to reduce electric bills? Produce more energy & cut the red tape that stops us from doing it. Pretty simple, it’s not rocket science.

Raindrops can bounce and then roll down a slope, picking up sand as they go. The sand-covered balls transport up to 100 times more sediment downhill than drops that don’t roll, a fact that could help make more realistic computer models of soil erosion and land change. News from Science
