Laser Beam Guidance for Oshkosh Air Show
Because general aviation aircraft often fly at relatively low altitudes, today's strongest lasers may pose a threat to the safety of the flight in all flight regimes. The FAA assures the AOPA, EAA and other pilot's association not to worry it will not be using any high powered lasers like was used against the Delta Heavy on its way into Salt Lake City or the many others we heard about in the news. Currently you have probably heard on the news that the FAA wants to use these lasers to prevent pilots from entering restricted airspace, especially around Washington DC or Crawford TX, etc. According to NORAD officials, the ground-based laser system uses safety-tested low-level beams of alternating green and red laser lights to alert pilots that they are flying without approval in designated airspace. This system would be used when the aircraft in question cannot be contacted on VHF voice radio by ATC.

Cracking Aircraft Windows with Directed Sound Waves
Some of these uses include communication, non-lethal weapons and high-energy lasers. Such a weapon would be inexpensive to use and save millions of dollars in anti-aircraft missiles, which often fail to hit their mark when the enemy has sufficient counter measures. A weapon of this type, which can crack windshields of aircraft would deter manned aircraft from entering a safety zone containing our military or civilian assets. When even a crack appears pilots must take action as the concerns of loss of cabin pressure take priority. Often flights with breaches in the pressurization system are forced to land or fly below twelve thousand five hundred feet where the oxygen percentages in the air are livable for humans.
