NASA’s X-59 Quesst: Overturning the 50-Year-Old Supersonic Speed Limit

NASA is addressing the longstanding ban on civilian supersonic flights over land by developing the X-59 aircraft, which aims to minimize sonic booms to mere “thumps.” This initiative could lead to regulatory changes that prioritize noise level over speed, potentially doubling air travel speeds over land while ensuring safety, sustainability, and reduced noise pollution.

Fifty years ago, the U.S. federal government banned all civilian supersonic flights over land.

The rule prohibits non-military aircraft from flying faster than sound so their resulting sonic booms won’t startle the public below or concern them about potential property damage.
