Step 4--Loading the 737

The Boeing 737 from JFK to Logan in Boston


The new Boeing 737s and 747s have turbofan engines that are 20 percent more efficient. The bodies and wings of the new Boeings are made of 1/2-inch thick carbon fiber which is extremely light, and many times stronger than riveted aluminum. The riveted aluminum eventually suffers metal fatigue and sometimes rips off during flight--a problem with the older 737s.
