West Point Glee Club stages airport flash mob performance

CHICAGO, Illinois (WABC) -- There was a special treat for travelers at Chicago's O'Hare Airport.

The world-renowned West Point Glee Club staged a flash mob performance at the airport on Thursday. They were joined by the USO of Illinois inside the American Airlines Terminal.

The group continued to grow throughout the performance, with singers appearing on two levels.

O'Hare Airport says it was a perfect way to honor those who served ahead of Veterans Day.
