On March 26th, a massive container ship called the Dali ploughed into Baltimore's Francis Scott Key Bridge, a major overpass just outside the city's port. The collision caused the bridge to dramatically collapse, sparked a search and rescue mission for survivors. It also cut off a busy shipping lane in and out of the Port of Baltimore. So what do we know about the collision? And what could the impacts of the latest maritime disaster actually be? On this emergency episode of Odd Lots, we speak to Sal Mercogliano, a professor at Campbell University and the host of the What Is Going On With Shipping? show on YouTube, about what we know so far.
