Federal authorities are investigating this morning after an alarming incident on the taxiway of the world's busiest airport seen here on airport runway, security camera video, we just hit something on the taxiway. Could you tell us what it was a large delta plane coming towards the camera with more than 200 people was heading to the runway about to fly to Japan when the tip of its wings here crashes into the back of a smaller regional jet with more than 50 people on their way to Louisiana. We were settling in getting ready for a long 15 hour flight and all of a sudden there was a bomb and it was, it was a hard journalists from our local stations in Cincinnati and Tampa were on the smaller plane. This video from WCPO in Cincinnati shows part of the tales sitting on the taxiway. People on the smaller planes say no one was hurt but it was still frightening. It felt and sounded like a car crash. There was, you know, kind of that crunch there was there was that push that you get oftentimes when these kinds of on the ground collisions occur. Weather is involved it's rain, it's night time and so it's lower visibility. This was a bright sunny day. The numbers show that there was a significant increase in the number of close encounters at us. Airports in 2023 those numbers took a slight drop in 2024. Experts say the reasons are complicated and one of them is a shortage of air traffic controllers. All of the passengers on both of these flights were put on other planes. Steve Osami ABC News Atlanta.
