Learning the answers to what happened:
…it may be that the crew, found at their seats when the sub was raised with no evidence of an attempt to abandon ship, may have been knocked out by the concussion of an explosion so close by, said Lt. Gov. Glenn McConnell, a member of the South Carolina Hunley Commission.
“I think the focus now goes down to the seconds and minutes around the attack on the Housatonic,” he said. “Did the crew get knocked out? Did some of them get knocked out? Did it cause rivets to come loose and the water rush into the hull?”
The final answers will come when scientists begin to remove encrustations from the outer hull, a process that will begin later this year. McConnell said scientists will also arrange to have a computer simulation of the attack created based on the new information. The simulation might be able to tell what effect the explosion would have on the nearby sub.
Maria Jacobsen, the senior archaeologist on the project, said small models might also be used to recreate the attack.
A fascinating archaeological project.
