IvanPelt1 asks: Are explosives not an option? Can't they collapse the well with explosives?
Mark Strassmann reports that an explosion of that magnitude would tear up the sea floor, probably tear out the blowout preventer and then the well would bleed out until it runs dry, bleed out uncontrollably.

CBS News Answers Your Oil Spill Questions
One viewer asks: Why so much emphasis on the oil spill environmental problem and so little on the 11 lives lost, and other crew traumatized by the blast?
Chip Reid answers that the brother of one of the victims testified today and he condemned the CEO of BP. Christopher Jones, a brother of one of the victims, said, "I want to take this opportunity to address the recent remarks made by Tony Hayward, CEO Of BP. In particular, he publicly stated he wants his life back. Well, Mr. Hayward, I want my brother's life back. And I know the families of the other 10 men want their lives back.
Reid says later this week President Obama will be meeting at the White House with families of the victims.
