Teacher Brian Ludmer, 29, was on his way to Chicago for a wedding. He was in a security line when the shooting started.
A bullet hit his calf and shattered a bone. He crawled away and hid in a small storeroom. Ludmer was rescued by police.
"The feeling of relief after hearing the voices and peeking out and seeing that it was in fact police was, I can't even describe. And they pulled me out," said Ludmer.
The officers put him in a wheelchair and raced him out of the airport.
Doctors say he'll recover.
