What could potentially be hazardous in a Warning Area?

In a Warning Area, the primary focus is on activities that pose a potential hazard to aircraft flying through or near the area. High-power military exercises are particularly significant because they can involve the use of live munitions, large explosions, or other activities that create significant hazards for any aircraft that might inadvertently enter the area during such operations. The nature of these exercises means that safety protocols need to be strictly adhered to, and the airspace may be restricted or closed to non-participating aircraft to mitigate risk.

While low-flying commercial aircraft, activities that could interfere with air traffic, and uncontrolled glider flights are indeed considerations in airspace management, they do not inherently possess the same level of immediacy in terms of catastrophic risk as high-power military exercises do. The potential for injury or damage is much higher with military operations, thus making them a critical factor to be aware of in a Warning Area.
