It’s surprising how many of our categories this unused Mike Roberts card C16526 falls into.  The caption is short but pithy with nothing but proper nouns.  One of them:  this is Tugboat Ann Brent.  Usually we only search aircraft records, but in this case we looked into Google for the tugboat, and found this:  “… on June 11, 1984, the U.S. towboat ANN BRENT, which was downbound in the Mississippi River pushing a 4-barge tow, collided with the upbound Greek tankship MANTINIA. As a result of this accident, the lead barge in the tow sank and discharged its entire cargo of No.6 oil into the river. The other barges in the tow were damaged to a lesser degree, but none of their cargoes were spilled. The MANTINIA sustained serious damage to its bow. No deaths or serious injuries resulted from this accident. The total damage to all vessels involved in this accident was estimated to exceed $500,000. The National Transportation Safety Board determines that the probable cause of this accident was the ambiguity of the meeting agreement reached by the ANN BRENT’s operator and the MANTINIA’s pilot over the bridge-to-bridge radiotelephone.” Thought you’d like to know.  Grade: 1
