What should you do to help alert other aircraft about a laser incident?

Reporting the incident to controlling agencies is crucial because these organizations have the proper channels and authority to address aviation safety issues effectively. Such reports are essential for tracking laser incidents that pose a risk to pilots and aircraft. These agencies often work to mitigate the risks associated with lasers by providing alerts to other pilots in the area, investigating the incidents, and implementing safety measures.

Posting on social media, recording the event for personal reference, or notifying local news outlets would not directly contribute to the immediate safety of flight operations or inform relevant authorities who can take action. Therefore, contacting the appropriate controlling agencies is the most responsible and effective course of action to enhance aviation safety after a laser incident.
