Today our modern military scientists have found many uses for directed energy beams. Some of these uses include communication, non-lethal weapons and high-energy lasers. Directed sound waves and harmonics maybe the answer to stopping manned aircraft in the battlespace on its way to find our blue force as its next target. Using such directed waves we can penetrate and crack aircraft canopies, rendering the aircraft useless to continue the mission. Or so disrupt the enemies mission that it is forced to turn back completely and abort or even force the enemy pilot to eject immediately.

Currently we have talking glass technologies, which vibrate windows and can be used to whisper sounds. These same technologies, which are currently produced with acoustic transducers attached to the windows can also be replicated from a distance with directed sound. Since glass, Plexiglas etc are brittle a certain type of vibration will cause them to crack and thus a breach in the aircraft at altitudes above a certain height become immediate problems for the pilot, taking precedence over mission and going to the heart of a human
