Deja'vu Oil Spill 30 years later

In 1979 there was a oil spill in the gulf of mexico almost identical to the one we are dealing with now. The similarities are frightening, and even the different ideas and techniques they are using to try and stop stop the oil spill are identical those ideas used over 30 yeas ago that didn't work then and they aren't working now. So how come over 30 years later after BP has said they are more technologically advanced are we still doing things the way they were done in 1979?

As the reporter for MSNBC said, the only advancement Oil Companies have made is that they can now drill to deeper depths nothing more.
