1964  A U.S. Coast Guard ice skiff rescued 25 persons from an ice flow that had broken loose from the shore near Camp Perry, Ohio.  A similar rescue took place almost simultaneously at St. Clair Shores, Michigan when another Coast Guard ice skiff and a police helicopter removed five more from an ice flow.

1987  Coast Guard attorney LCDR Robert W. Bruce, Jr. became the first member of the armed forces to argue a case before the Supreme Court in uniform.  He represented the Coast Guard in Solorio vs. United States.

1989  United Airlines Flight 811, a Boeing 747 with 337 passengers aboard, suffered an explosive decompression resulting in the loss of nine passengers 17 minutes after departing Honolulu as it climbed between 22,000 and 23,000 feet. The aircraft subsequently landed having lost engines three and four. A Coast Guard HC-130, two helicopters, and CGCs Cape Corwin, Mallow and Sassafras searched for the lost passengers but found none. The units then assisted in the retrieval of debris.
