All was going smoothly on my way to visit my daughter in Mississippi. They announced we were boarding our flight from Dallas to Jackson. The line was moving forward and then it seemed all boarding had suddenly stopped. I saw a gentleman looking out the window at the jet bridge and asked him what was going on. He said there was a worker down and it seemed to be a medical emergency. After a while, I noticed two men talking and I felt they knew more about the incident so I walked up to them and asked them what had happened. They said they were boarding the plane and noticed a man pinned between the nose of the plane and a big piece of machinery that was seemed to be out of control. They ran down the jet bridge and miraculously pushed the machinery off of the man and he collapsed to the ground. As we were talking and waiting for another plane, we were informed that the worker was taken to the hospital and seemed to be doing ok. These two real life heroes are true lights and I will forever be in awe of their quick thinking and bravery!
