Robert Kaluza, a well site manager for BP Plc during the 2010 explosion on board the Deepwater Horizon oil rig, right, arrives at federal court with his attorney David Gerger in New Orleans, Louisiana, U.S., on Wednesday, Nov. 28, 2012. Kaluza, who supervised testing on the Macondo oil well, and another site manager Donald Vidrine, were charged Nov. 15 with involuntary manslaughter, seaman’s manslaughter and Clean Water Act Violations. The U.S. alleges that Kaluza and Vidrine ignored multiple indications that the well wasn’t secure before the explosion that killed 11 aboard the drilling rig. Photographer: Derick E.
