We now have a better view of the St. Louis Good Friday Tornado that struck Lambert Field over the weekend. This surveillance video shows just how abruptly the tornado descended on the airport.

If you've traveled to an airport in the Midwest you've likely noticed the signs outside the bathrooms that say "Emergency Tornado Shelter." These three TSA agents smartly heed that advice and escape into a bathroom just seconds before debris is sent down the hall.

They work. No one died or was horribly injured.

Despite what happens, remember, it's not necessary to select gender-appropriate shelters. Just pick the closest one.
