A test flight of the megarocket unleashed a massive sonic boom—at least 10 times louder than the roar of a Falcon 9 rocket—as SpaceX sets its sights on launching it up to 100 times a year.

An independent researcher found that noise recorded miles away from the site of a recent test flight was equal to standing 200 feet from a Boeing 747 during takeoff.

Scientists have found that SpaceX's massive Starship rocket is so loud, its sonic boom could cause property damage back on the ground. Measurements taken during the Elno Musk-led company's fifth test flight last month suggest the resulting wave of sound and air pressure could pose "greater risk of structural damage,
