Second, the technical support is also a factor that Boeing worries about. The major competitor of
Boeing, Airbus, declared that 7E7 was a salesperson’s dream and engineer’s nightmare. Why do they say
so? This is because 7E7 was claimed to be the first commercial aircraft that primarily build with carbon-reinforced material which are stronger and lighter than traditional aluminum. However, the compositematerial was suspected as a contributory cause to a 2001 plane crash in New York. Therefore, regulatoryscrutiny is needed. Moreover, the company promised to provide a jetliner which has the ability to travellong and short distance has also made engineering obstruction. Traditionally, two versions of plane withdifferent wingspans are needed to make long and short distance travel. Boeing engineers considered thepossibility of snap-on wing extensions which is more costly as well as technically feasible.
