It actually happens a lot...
"In October 1996, on a clear night the 754 foot Greek oil tanker Aegeo struck the tower, causing severe damage. It was discovered that the light was not functioning when the tanker hit the tower (i.e. at the time of the allision). The Aegeo's captain was later found to be at fault. Three years later, in September 1999 after repairs were deemed insufficient, the old structure was razed by the U.S. Army Corps of Engineers and replaced with a new tower. The new tower was built about 1.5 miles East of the old site, and is approximately 76 feet above mean low water, and the 60,000 candle-power light is visible for 18 miles.
In January 2001, the 492 foot Maltese freighter Kouros V struck the new tower, shortly after the repairs from a previous allision had been completed.
On November 3, 2007, the tanker Axel Spirit struck the tower . No injuries or pollution were reported. "
