Security means different things to different people in different places and at different times. The absence of a single, universally accepted definition of security makes the uninitiated to regard such an important word as “a matter of perspective.”
The military aviation community has always been indoctrinated to maintain situational awareness (SA) in all phases of air operations. This is the very reason pilots have pre-flight briefings, emergency procedures review and crew resource management techniques and procedures.
It is industrial security when it involves individual corporations or when it deals with crisis management of a company. At the flick of a finger, this can escalate into a national security concern like the Dos Palmas incident in Palawan. What started a simple kidnapping case in Dos Palmas subsequently became a national security issue.
