""Through a combination of sensors embedded in the drilling equipment and sophisticated instrumentation that is capable of sensing distance to the well casing, BP engineers and the federal science team have concluded that the Development Driller III relief well has intersected the Macondo well," retired Coast Guard Adm. Thad Allen, the federal spill commander, said in a statement."
