A new security screener that people can simply walk past may soon be coming to an airport near you. Last year, U.S. airports nationwide began adopting HEXWAVE—a commercialized walkthrough security screening system based on microwave imaging technology developed at MIT Lincoln Laboratory—to satisfy a new Transportation Security Administration (TSA) mandate for enhanced employee screening to detect metallic and nonmetallic threats.

The Transportation Security Administration has relaxed one of its policies for boarding domestic flights. Passengers are no longer required to remove their shoes when processing through security lanes in U.S. airports.

The Transportation Security Administration is quietly sunsetting a common security checkpoint procedure at some airports. Is your airport on the list?

TSA is currently hosting PreCheck mobile enrollment events near major U.S. military installations. Enrollment costs range from $77-$85, depending on the provider, with membership remaining valid for five years. Providers include CLEAR, IDEMIA and Telos.
