Prior to the oil spill, BP promised they could skim half a million barrels of oil a day in a worst-case scenario.

So far, though, cleanup workers hired by BP have skimmed only the surface, using shovels or sifting machines to remove oil.

The company is planning a deeper cleaning program that could include washing or incinerating sand once the leak is stopped off the coast of Louisiana.

So what went wrong, and why is this taking so long?

CNN's Brian Todd has been following this story from the beginning and says the weather may be a factor.
