People tend to take for granted the technological advances inherent in today’s jet airplanes. For example, the Boeing 777, which was first flown commercially by United Airlines in 1995, has unbelievable power. Each of its gigantic GE-90 engines produces more than 111,000 horsepower, and during take-off, the engines take in 2 million cubic feet (56,634 cubic meters) of air per minute. Needless to say, transportation technology has come a long way since the days of the RMS Titanic, the state-of-the-art ocean liner completed in 1912. All together, the Titanic’s steam engines, powered by 159 coal furnaces, only produced about 46,000 horsepower.
