So, is this mud or oil? Apparently, there is no definite word at this time.
Update 5-27-10 8:00 p.m. EDT:
Fox News just announced that after a pause, BP has begun the ‘Top Kill’ once again. I have no idea why that is not reflected in the video, but it would obviously take some time to feed the mud in the device said to be 5-stories long.
Find information on the ‘pause’ here.
