All nine people on board were uninjured in the incident on Monday (local time), US media reported, citing the military. They freed themselves from the plane and were then rescued from the water, wrote the New York Times, citing a spokeswoman for the base.

The cause of the incident was initially unclear. Local media reported difficult weather conditions with rain and clouds that day. Honolulu, the capital of the US state of Hawaii, is also located on the island of Oahu, where the incident occurred.

Environmental toxins: Barriers designed in the water

Photos and videos in local media showed the plane sticking out of the water after the incident. The images were reminiscent of the plane that made a spectacular emergency landing on New York’s Hudson River in 2009 without anyone being injured.

CNN reported that it was a P-8A Poseidon reconnaissance aircraft. The machine, which has the fuselage of the Boeing 737 passenger aircraft, can transport both torpedoes and cruise missiles and is used, among other things, in reconnaissance missions.

In order to prevent the spread of dangerous substances, barriers were placed in the water, NBC News reported, citing information from the US naval base. This is located in Kaneohe Bay, which also contains coral reefs, a breeding site for hammerhead sharks and a marine biology research institute at the University of Hawaii, wrote the Hawaiian newspaper “Star Advertiser”.
