A solar-powered airplane finished crossing the United States on Saturday, landing in New York City after flying over the Statue of Liberty during its historic bid to circle the globe, the project team said. The spindly, single-seat experimental aircraft, dubbed Solar Impulse 2, arrived at New York's John F. Kennedy International Airport at about 4 a.m. local time after it took off about five hours beforehand at Lehigh Valley International Airport in Pennsylvania, the team reported on the airplane's website. Such a pleasure to land in New York! For the 14th time we celebrate sustainability," said the project's co-founder Andre Borschberg on Twitter after flying over the city and the Statue of Liberty during the 14th leg of the trip around the globe. The Swiss team flying the aircraft in a campaign to build support for clean energy technologies hopes eventually to complete its circumnavigation in Abu Dhabi, where the journey began in March 2015.

Bull sharks are mainly found in the warmer and shallower coastal waters of the southern hemisphere. The bull shark is one of the most common species of shark found worldwide. The bull shark is able to inhabit both salt and fresh water sources just as happily, with one bull shark known to have swum 4,000 km up the Amazon River in South America, finally ending up in the mountainous Peru. The bull shark is well known for its unpredictable and aggressive temperament and is thought to be one of the most dangerous sharks towards humans. This is probably because the bull inhabits coastal waters and rivers and is therefore more likely to come into contact with swimmers and water sports enthusiasts.
The bull shark is an effective and dominant predator in its environment and so has no real natural predator itself. Bull sharks are occasionally hunted by the bigger shark species such as the tiger shark and the infamous great white shark.
