The Torrey Canyon oil spill was one of the world's most serious oil spills. The supertanker SS Torrey Canyon ran aground on rocks off the south-west coast of the United Kingdom in 1967, spilling an estimated 25–36 million gallons (94–164 million litres) of crude oil. Attempts to mitigate the damage included the bombing of the wreck by aircraft from the Royal Navy and Royal Air Force. Hundreds of miles of coastline in Britain, France, Guernsey, and Spain were affected by the oil and other substances used in an effort to mitigate damage.
