NEW ORLEANS (AP) — Workers on the drilling rig that exploded at the outset of the 2010 Gulf of Mexico oil spill catastrophe were “trying to get it right” as they monitored BP’s well for signs of trouble before the blast, an expert witness for the company that owned the rig testified Monday.

“They just misinterpreted what they were seeing,” well control expert Calvin Barnhill said on the 13th day of a trial over the disaster. “I don’t think anybody out there intentionally misinterpreted this situation.”
