The Wallenius Wilhelmsen cargo tracking website still claims that the Liberty will arrive in New York today, and the latest ship position suggests it might actually happen!
This Great Circle Calculator suggests that the Liberty was less than 300 miles out of New York this morning, and can cover about 400 miles per day (although presumably less when close to land!) … so it looks like the GPs may arrive on land overnight tonight 🙂
