English: The "Big Yellow" - A very familiar face This Sea King passes over our house that often that we regard it as part of the family. The "Big Yellow" has a distinctive sound which distinguishes it from the many other helicopters which pass daily over the house. When it flies past in the afternoon it is generally an exercise flight, but a late at night or an early in the morning flight generally means trouble. Its destination can also be reckoned from its height. A North Snowdonia incident equals a fairly low flight; a South Snowdonia incident it goes over as a noisy dot in the sky. A rooftop-hugging flight west to east usually means that it is carrying a diving accident victim from the Dorothea Quarry to a decompression chamber. http://www.raf.mod.uk/rafvalley/aboutus/seaking.cfm
