Transcript for Man Runs Onto Tarmac to Stop United Flight
Coming up on 7:18 with a man who ran under the tarmac after the door closed on his flight. Our aviation correspondent David Kerley at Reagan national airport with the story. Good morning, David. Reporter: Good morning, George. A serious safety issue. Take a look at these pictures of this man running after the plane. That man running on the tarmac must have stunned the tug driver pushing back the united jetliner in Denver. The would-be passenger carrying a bag stops the tug, insists he be let on to the jetliner. I have never had a passenger try to chase down an airplane I was flying nor have I seen this happen. Mark Raymer was late to the gate. The doors were closed. He went through an emergency door, down the tarmac and started his mad dash. Airport workers quickly surround the man so that the jet can't continue. On Monday, Raymer pleaded guilty to tampering for the August incident sentenced to two years' probation, 100 hours of community service. This is a crime and it has to be treated that way because it's simply too dangerous out there. Reporter: While this was an unusual tarmac breach it's not the only one we've seen from the teenage stowaway who jumped a fence in San Jose and to drivers some impaired by drugs or alcohol busting through fences and driving near aircraft. As for Raymer's reason, according to reports he was heading to his 40th high school reunion and apparently didn't want to miss it. We called Raymer, he didn't want to talk to us so, George and Amy, we don't know if he ever made it to his reunion. Can't blame him for not wanting to talk.
