Undercover Air Marshals Are Real
It may surprise you that air marshals can be on both local and international flights. Due to the nature of their job, they must maintain a low profile, making it impossible to publicly disclose their exact number or the flights they are assigned.
They are essential in safeguarding passengers from potential terrorist activity, aviation piracy, and other crimes. You might expect them to be on every aircraft. However, the percentage of flights with air marshals is about 5 percent.
