A hearing in Kenner, La., into possible shortcuts leading up to the BP blowout was cancelled after some witnesses didn't show, others couldn't remember, and one took the Fifth.
"KENNER, LA. -- Tuesday was supposed to be a banner day in the government's hearings into the Deepwater Horizon disaster.
Finally, a federal panel investigating the blowout was going to hear from some of the top men who represented oil giant BP on the rig, and from a subsea supervisor who could discuss the infamously ineffective failsafe known as the blowout preventer, or BOP.
Instead, one witness said he was off the rig and out of the loop when pivotal events transpired. Another generally said he didn't know, couldn't recall and was just a trainee too inexperienced to opine.
Two more witnesses stayed away altogether -- one citing medical reasons and the other invoking his Fifth Amendment right. "
