NASA is hoping that will one day be a reality as it works to prove that quiet supersonic commercial travel is possible. It’s a test to determine how to best study people’s reactions to quiet supersonic jets. LBFD is NASA’s low boom flight demonstrator—a supersonic aircraft that reduces the sound of the sonic boom. With low boom flights, NASA said it “intends to gather data on how effective quiet supersonic technology is in terms of public acceptance.”The Federal Aviation Administration generally prohibits supersonic flight over land. But because the LBFD won’t be completed until 2021, NASA is simulating the sounds for now.
