The giant cargo ship Ever Given has finally been unstuck from where it ran aground in the Suez Canal, snagging traffic for nearly a week. According to Bloomberg News, salvage teams were able to finally dislodge the 400-meter-long ship by removing 27,000 cubic meters of sand. More than 450 ships are clogging the vital canal—waiting to enter, or en route—and it’s still not clear when the newly refloated ship will be able to move aside. The Suez Canal Authority said Monday that further efforts to move the boat will take place later in the day, but rescue effort officials have urged caution, saying that ending the blockage won’t be “a piece of cake.”
