In large buildings to prevent sound pollution often double paned glass is used with music or flowing air between the panes, this works very well and is sufficient to prevent the noise. Since many commercial airliners have double paned glass already if we are careful to watch the harmonics as to not cause structural problems to the aircraft (remember the Comet), then we propose hypersound or ultrasonic sound within the panes to prevent laser light from entering the cockpit and inhibiting or blinding the pilots.

As we recently saw with the Delta Airlines scare where the pilots were nearly blinded by what they described as a laser light, we believe that this idea may be the answer.

We believe such a device could be easily and cheaply built and installed in airliners. Such a device and use of hypersound might even be an option for those who fly into combat where THEL systems are guarding the region. Once seen by the enemy it maybe too late to dodge the lasers, as it takes such a small time to burn the retinas of a pilots eyes.

It is possible that such a method may give the pilots a few seconds extra time to put on anti-laser head gear.
