    • ‘Despite its name, the sonic boom cloud doesn't always come with a sonic boom, and it's not a shock wave of the sound barrier being broken.’
    • ‘As a result, an aircraft creates a sudden discontinuity in pressure and temperature called a shock wave as it breaks the sound barrier.’
    • ‘That is a jet supposedly breaking the sound barrier.’
    • ‘In 1969, Concorde prototype 001 broke the sound barrier on a test flight in France.’
    • ‘Flying just below the sound barrier, the ride tends to be bumpy and unpredictable because shock waves form around the airplane as it approaches Mach 1.’
