The Greatest Navigational Journey

    In 1787 Captain Bligh was given command of “The Bounty”, a three-year-old merchant ship. His mission was to transport breadfruit plants from the island of Tahiti to the West Indies. We know the popular story of this voyage and the rebellion, in which Bligh has been presented as hard, violent and thoroughly unpleasant captain. However, there is quite a lot of evidence to suggest that this picture is far from being true. He seems to have been unusually thoughtful about the health and welfare of his men. For example he made sure that his crew got exercise, insisted on cleanliness on his ship, and adopted the practice of giving them a drink which prevented scurvy every day.

    When Captain Bligh arrived in Tahiti, it became clear that it would be some months before the breadfruit trees were ready to be taken to the West Indies. Instead of going off right away, he gave his crew extended shore leave. This may have been a mistake as many were unhappy about leaving when the time came. Finally, on the return journey the rebellion took place. The ship was under the command of the rebels and Captain Bligh had to leave in a small boat.

    Captain Bligh's achievement was to get to dry land successfully. It is one of the supreme examples of seamanship. Apart from Bligh there were 18 members of his crew sailing in an open boat about 23 feet long and 7 feet wide. They took with them 25 gallons of water, 150 pounds of bread and 30 pounds of pork. They had no guns or other weapons. The boat was so low in the water that it seemed likely to sink at any time. On one occasion Captain Bligh tried to land on an island to get more water. He and his men were attacked by hostile natives and one of the crew was killed. At this point Bligh decided to sail directly to the Dutch settlement on the island of Timor without stopping. The distance was about 4,000 miles. The voyage took about 42 days and he had no advanced navigational equipment. However, his skill and commitment proved equal to the task and amazingly no one else died. It was truly a remarkable achievement.

    Flying devices called drones(无人机) may be one of the most important technologies of the future.

    The number of jobs for people who know how to design, build and control them is increasing. Because of this increase, several U.S. universities have started offering degrees in unmanned aircraft systems, or UAS.

    One of these universities is the University of Washington in Seattle. Ward Handley is seeking a master's degree in UAS at the university. When the drone program first began, he did not think it was a good idea. “Drones can be used to invade privacy(侵犯隐私).” He said. But later, Handley changed his opinion. He said, “I think there are good enough purposes for them.”

    The FAA (the part of the U.S. government that controls air travel and traffic) is creating new rules to control the use of drones, however. A new law requires drone owners to register(登记) their drones. People who do not register their drones could face fines of up to US$20,000.

    The new rules may also present problems for students. One problem is finding a legal place to fly.

    Students at Blue Mountain Community College fly inside the college gym. In Seattle, University of Washington students test their drones in a big room.

    Christopher Lum, a scientist at the University of Washington, helps students explore how drones can safely share the sky with regular aircraft. Lum explained why they test drones inside a building, “We need to register our aircraft and get permission to fly outside. That process can take months.”

    At this time, Kansas State University is the only school with permission to offer unmanned aircraft flight classes to students outside. The FAA selected Kansas State University and 15 other universities to be part of a national research group.

    Lum and some of his students recently moved their research to Australia. Australia has fewer rules limiting drones. A professor at Western Washington University also took his department's drones to Canada for the same reason.
