An airplane is a flying machine.
Less than 100 years ago, even the fastest ship took more than a week to cross the Atlantic Ocean. Today most jet airliners (large passenger planes) can make this 4,800-km (3,000-mile) journey in less than seven hours. Airplane are the fastest way to travel because they can soar straight over obstacles such as mountains and ocean. Modern airplane are packed with advanced technology to help fly safely and economically at great speed. Sophisticated electronic control computer-designed wing help cut fuel costs. And airframes are made of metal alloys and plastic composites that are lightweight and strong.
Airplanes are sometimes called just 'planes. All airplanes have wings. Gliders are airplanes that do not have engines.
