The Final Boom-Boom

The Shuttle orbiter makes twin booms as it passes through the Sound Barrier over the Space Coast. Illustration source: Florida Today.

Twin sonic booms were heard across the Space Coast this morning for the last time in Shuttle history.

I videotaped the sound as it passed over our north Merritt Island home just before dawn. Click here to listen. (Turn up your stereo speakers!)

Florida Today published an article July 20 explaining the phenomenon.


  1. Actually the sonic boom does not happen when the shuttle passes through the sound barrier, but when it flies supersonic.

  2. However it's produced, it sounded like very close shotgun blasts. Wow, I had no idea! Thanks Stephen!
