Alwin Landry, master of a boat tethered to the rig on the night of the explosion, said he noticed mud dripping on him like "black rain". Suspecting that he had a broken hose or a ruptured derrick, he called for help, but while waiting for a response, he testified, he heard a high-pitched hissing sound, followed by a large explosion. Debris flew through the air. Moments later, he said, he saw three people jump from the rig into the Gulf of Mexico. "Mayday," he heard from the rig, followed later by, "Abandon ship."
