Time was running out，and Mark Dickinson wasn't sure whether he'd get to see his dying 2yearold grandson one last time.A long line at Los Angeles International Airport's security checkpoint had kept him from getting to his gate on time.
His grandson Caden would be taken off life support in a matter of hours in Denver，Colorado，with or without his grandfather's presence.
“I was kind of panicking(惊慌)because I was running late，and I really thought I wasn't going to make the flight，”Dickinson said.
That's when a pilot from Southwest Airlines stepped up and held the flight at the gate until Dickinson arrived.The pilot was standing by the gate waiting for him when Dickinson arrived in socks，so rushed that he just grabbed his shoes at security and ran through the boarding gate.
