1764  Sandy Hook Lighthouse, at the south point of the entrance to New York Harbor, was first lighted.  Today, its octagonal tower, built by Mr. Isaac Conro of New York City with money collected by a group of New York merchants, is the oldest original light tower still standing and in use in the United States.

1942  After the Battle of Midway (4–7 June), CGC Taney anchored at Midway Island after escorting USS Regulus (AK-14) there.  For the next four days Taney conducted SAR operations in the waters around Midway, the island itself, and then “went out into the Pacific Ocean to look for survivors reported by plane.”  Taney departed Midway Island on June 16 and escorted Regulus back to Honolulu.

1966  Finding itself disabled and adrift two miles from Cape Kubugakli, Alaska, the fishing vessel Katy C radioed for assistance.  A Coast Guard helicopter, after ascertaining that the ship was unable to anchor by herself, took her in tow until she was out of danger.
