What to put in the hole?

A containment dome is a 4-story, 70 ton structure that the company plans to lower to stop one of the three leaks. The company was also planning to install a shut off valve but did not! A blowout preventer is a device that is used to stop leaks, but in this case it created a big explosion.One of BP's investors is FBR Capital Markets. With the spill and no way to stop the leaks, FBR lost their entire investment. One thing I would do to prevent this from happening again is I would hire a special team to make sure we use shut off vavles everytime we decide to spill.
