If an individual is asking suspicious questions about aircraft security, who should be notified first?

When an individual is asking suspicious questions about aircraft security, it is crucial to prioritize the safety and security of the aviation environment. Notifying local law enforcement and the local FBI field office first is essential because these agencies are specifically trained to handle security threats and suspicious activities.

Law enforcement has the resources and authority to investigate potential threats to public safety, while the FBI has jurisdiction over federal matters, including those related to aviation security. Their involvement can lead to a timely and effective response to any potential risks, ensuring that appropriate measures are taken to protect both individuals and the aviation system as a whole.

The other options involve agencies that, while important in their respective areas, may not be equipped to handle immediate threats related to security. The aerial application business owner may need to be informed eventually, but they are not the first line of defense in addressing security concerns. Similarly, the local environmental agency and the Federal Aviation Administration have roles that do not directly focus on responding to security threats and might delay the appropriate response needed to address the suspicious activities.
