Tune in Friday at 9p ET as Megyn Kelly sits down with three American heroes who foiled a would-be terrorist on a high-speed train in France.

Back in August, U.S. Airman Spencer Stone, National Guardsman Alek Skarlatos, and Sacramento State University student Anthony Sadler suddenly found themselves in the spotlight when they tackled a gunman aboard a train in Europe, saving lives and becoming worldwide heroes.

While each of the men have spoken to the media since, no one has yet to interview the three boyhood friends together until now.

Don’t miss Megyn’s exclusive sit-down with the three young men on Friday, Sept. 11 at 9p ET on "The Kelly File."
