I don't think that the shock waves would have made much noise - certainly not as much as the engines:) Of course, if the aircraft had been supersonic then there would have been a 'boom' as the air rushed in to fill the hole bored by the aircraft. Heh - if it had supersonic that close to the water we'd have probably seen the water surface actually being lifted up and not just disturbed too:) I believe that the visual distortions we can see are due to the changing density of the air, caused by the shock waves, which affect it's refractive index - it's a similar effect to heat-haze shimmer. That's the first time I've actually seen it caught on film though - or should that be ccd?
