I don't see ear muffs and plugs surely cant be enough.
Ouch!

re: Check out
that isn't a sonic boom...
Its a pressure shockwave, causing the moisture in the air to condense suddenly...
its still cool...

Watch again slowly and see that the aircraft passes the wave.

I watched that video clip with my trusty webTV receiver...it took me about 5 minutes to download with a 56 kpbs modem! I liked the way the ocean below the jet was agitated as the conical shock wave hit the water's surface.
Was it a sonic boom? I did notice toward the end of the clip, as the jet is flying right to left and viewed sideways by the camera, that the shock wave appeared to be on the trailing end of the jet...isn't this what happens when a jet breaks the sound barrier and generates a "sonic boom"? If so, then those people observing it must have been almost blown out of their shoes when it hit them!

On 7/6/06, I found, in any overbalanced gravity wheel with rotation rate, ω, axle to CG distance d, and CG dip angle φ, the average vertical velocity of its drive weights is downward and given by:
Vaver = -2(√2)πdωcosφ
Vaver = -2(√2)πdωcosφ
