SUEZ, Egypt (AP) — Experts have boarded a colossal container ship that had blocked the Suez Canal for nearly a week before it was dislodged. Everyone is wondering what went wrong to cause the blockage that shook the global shipping industry and clogged one of the world’s most vital waterways. A canal pilot says engineers are inspecting the Ever Given for damage and trying to determine why it ran aground. The ship was safely anchored Tuesday in the Great Bitter Lake, a wide stretch of water halfway between the north and south ends of the canal after salvage teams succeeded in finally freeing the skyscraper-length vessel the previous day.
