Weather hampers efforts to contain oil spill
An oil skimmer is being put through its paces in the Gulf of Mexico, but bad weather means it may be longer than first hoped before officials know if it can work full-time sucking crude from the sea.
The Taiwanese skimmer dubbed "A Whale" was able to show off its flexibility during a weekend test in a 25-mile-square patch of water just north of the site where an April 20 explosion on the Deepwater Horizon killed 11 workers and started the worst oil spill in Gulf history.
