It's estimated that there are around 5,000 planes in the air over the United States at any given time. There are probably a couple of thousand more airplanes flying in other parts of the world, and about 500,000 people are in those planes.
A:A helicopter parent does not give a child enough space to grow and experience life on his own. The term was first used in a 1960s book, "Parents & Teenagers" by Dr. Haim Ginott's, where some teenagers used it to refer to parents who were overprotective of them.
A:The average speed of an airplane depends on the size and type of the airplane. A Boeing 747, which is a popular commercial plane, has a typical cruise speed of .85 Mach or 567 miles per hour when at 35,000 feet.
A:Commercial flights would take approximately 51 hours to fly around the world. The total flight time depends factors that include the weather, the plane's weight, the pilot, and starting or ending locations.
A:The airplane was invented due to a new century blooming and man's desire to discover new methods of transportation and discovery. While ground transportation, such as trains and cars, was making headway, a way to travel long distances without the complications of terrain had yet to be discovered.
A:Airplane travel allows for shorter travel times and travel efficiency; it allows people to see the world and it creates millions of jobs across the globe. The world is now global and there are no true borders thanks to air travel.
A:The most common cause of airplane crashes is human error. According to the BBC, up to 50 percent of all airline accidents can be attributed to pilot error, but the Baltic Aviation Academy suggests that the number may be as high as 70 percent. Frequent factors that contribute to human error resulting in a crash include striking wires, losing control of the plane or flying into the water or land.
A:A flying camera drone is a device that records images while going through the air and is either piloted remotely or automatically. Drones are also known as unmanned aerial vehicles or remotely piloted aircraft. They are aircraft without a human pilot inside.
A:The actual cost of a helicopter varies depending on many factors, including age, size and available features on a particular unit. As of 2014, basic helicopters typically start around $120,000 for a two-seat pre-owned unit, and can escalate to several million dollars for the large commercial or luxury models.
A:Attempts to create helicopters can be traced back to Leonardo da Vinci, but the first working prototype helicopter, the VS-300, was invented by Igor Sikorsky in 1939. The next model he designed was the R-4 in 1942, which was the world's first mass produced helicopter. Sikorsky pioneered the rotor configuration that is used on most modern helicopters.
A:The airplane has changed the world in numerous ways, especially by increasing the speed of travel, aiding international business and making the world more connected and globalized. Before the invention of airplanes, most people would never travel to faraway places because of the sheer amount of time it took to sail across oceans or to drive through countries. The airplane changed that.
A:Most people who have vertigo are able to fly. Potential problems include motion sickness or increased dizziness. Flying on a large commercial airline with a pressurized cabin helps to reduce both problems. Over-the-counter medications also help to reduce symptoms.
A:Modern 747 model aircraft, nicknamed "jumbo jets," can seat between 300 and 500 people. The exact number of seats depends on the type of 747 jet and the individual airline's configuration of the plane.
A:How fast a plane goes depends on the type of plane and other factors such as altitude and weather conditions. As of 2014, the Lockheed SR-71 Blackbird has the official record for a manned airplane speed, at 2,193 mph.
A:Immediately before takeoff, flight attendants typically remind passengers to fasten their seat belts and prepare for takeoff. However, the procedures vary depending on the airline. In addition to this statement, there is a long list of things covered before a plane takes off. A flight attendant usually conducts a demonstration that covers this information.
A:The Cessna Skyhawk, a single-engine plane, has a maximum cruising speed of 124 nautical miles per hour, which is just over 140 miles per hour ground speed. A Boeing 747 typically cruises at 567 miles per hour.
A:According to LiveScience, the fastest manned aircraft ever flown is the experimental X-15. As of 2013, the X-15 holds the world record for fasted speed achieved by a piloted aircraft: 4,520 miles per hour, which is 6.72 times the speed of sound.
