I’ve been following Sal @ What’s Going on With Shipping for a while. He’s very knowledgeable. He pointed out that the port anchor WAS dropped. But that’s insufficient to stop a huge ship like this quickly. There’s just too much energy in its motion to dissipate.
Here’s the latest from WGWS. Sal tracks the ship’s movement from dock to bridge.
