The Large Hadron Collider is a particle accelerator and is the largest of its type in the world. It is used for conducting experiments in theoretical physics and was built with a focus on determining whether the Higgs boson particle exists.
A:According to the National Oceanic and Atmospheric Administration, there are 5,000 planes flying in U.S. airspace at any given time as of 2014. NOAA also estimates that at least 87,000 airplanes fly over the United States every day, and only one-third of them are commercial flights.
A:A two-seat trainer helicopter averages flight speeds between 90 and 105 mph. A five-seat turbine helicopter can reach average cruising speeds between 130 and 145 mph. The maximum speed in some helicopters is about 255 mph.
A:The record for maximum altitude achieved by a helicopter is 40,820 feet. This record was set on June 21, 1972 by French aviator and test pilot Jean Boulet, who was piloting an Aerospatiale SA 315B Lama.
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:Airplanes are important, because they allow people and goods to be transported quickly over great distances and over all types of terrain. Before the advent of safe and convenient travel by airplane, journeys took much longer and were more difficult.
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:A scheduled flight is a trip by airplane, glider or other aircraft that has been planned for a certain time and date. Airlines sell tickets for scheduled flights to help travelers get from one destination to another. Ticket prices for scheduled flights vary depending on the airline.
A:Airplanes take longer to fly west than east because of high-altitude winds that blow from west to east. The Earth has four such wind patterns, and they are called jet streams. When planes fly from west to east, the jet stream helps accelerate the aircraft. When they fly in the opposite direction, the planes cannot fly as fast into the face of the wind.
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: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:The Large Hadron Collider is a particle accelerator and is the largest of its type in the world. It is used for conducting experiments in theoretical physics and was built with a focus on determining whether the Higgs boson particle exists.
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: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:Rules regarding packing razors in airplane luggage depend on the type of razor in question. Disposable razors and cartridges are allowed in carry-on bags, while most other types of razor must be secured in a checked bag.
A:It is almost impossible to know how many planes take off and land every day worldwide. There is an average of 23,000 scheduled take-offs and landings in the United States everyday. That number does not include private planes, chartered jets and other non-commercial aircraft.
A:According to Boeing, the 747-400 family of aircraft have 16 main landing gear wheels. The landing wheels are outfitted with structural carbon brakes that improve energy absorption characteristics and wear resistance, while also saving 1,800 pounds of weight when compared to previous brakes.
