It is a mixture of human biowaste and liquid disinfectant that freezes at high altitude. The name comes from the blue color of the disinfectant. Airlines are not allowed to dump their waste tanks in mid-flight, and pilots have no mechanism by which to do so; however, leaks sometimes do occur.

The most common method used by various wolfdog communities is phenotyping, a method that involves observing the animal's physical features. This method is often favoured for many in determining the degree of wolf and northern spitz-type dog that is in a wolfdog. However, a lot of criticisms have been made by opponents within some communities who tend to point out that phenotyping cannot always determine the wolf-contents accurately. Another challenge involves determining exactly the domestic breeds and wolf subspecies involved in the admixture due to the fact that dogs are known to come in various breeds while gray wolves in turn come in various subspecies with many different regional ecotypes hence have different physical features depending on the subspecies used in the breeding. Although wolves are often mixed with spitz types such as Siberian Huskies, Alaskan Malamutes, and German Shepherds, admixture between wolves with non-Spitz type dogs such as Poodles, Pit bulls, and Great Pyrenees also exist, the latter wolfdogs often having less lupine features.
 Question: is a german shepherd considered a wolf hybrid Context: The trophy has the engraving ``FIFA World Cup'' on its base. After the 1994 FIFA World Cup a plate was added to the bottom side of the trophy on which the names of winning countries are engraved, names therefore not visible when the trophy is standing upright. The inscriptions state the year in figures and the name of the winning nation in its national language; for example, ``1974 Deutschland'' or ``1994 Brasil''. In 2010, however, the name of the winning nation was engraved as ``2010 Spain'', in English, not in Spanish. As of 2018, twelve winners have been engraved on the base. The plate is replaced each World Cup cycle and the names of the trophy winners are rearranged into a spiral to accommodate future winners, with Spain on later occasions written in Spanish (``España''). FIFA's regulations now state that the trophy, unlike its predecessor, cannot be won outright: the winners of the tournament receive a bronze replica which is gold-plated rather than solid gold. Germany became the first nation to win the new trophy for the third time when they won the 2014 FIFA World Cup.
