What a reasonable person would do

I just heard BP will start spraying oil dispersant under water, “something that hasn’t been done before,” according to the report.

Is it just me, or is everything BP tries to do to stop their oil flow “unprecedented,” “never tried before,” “experimental,” “untested at this depth,” “new,” etc. It’s almost as though no one, anywhere in the industry, ever thought to prepare for, or test equipment and methods for, a blowout at this depth. Ya think?
