Strait of Juan de Fuca laser incident

On 4 April 1997, a Canadian Armed Forces helicopter was allegedly illuminated by a laser while observing the Russian merchant ship and suspected spy vessel Kapitan Man, which was in the Strait of Juan de Fuca in U.S. territorial waters near Port Angeles, Washington. The Canadian Air Force pilot and the U.S. Navy passenger, who was taking photographs of the ship, reported eye pain and claimed injuries consistent with laser exposure.
