Last Saturday I was at an air show with a friend . Jeff, my friend, is considering a careerin aircraft (1) and that's why he is interested in aviation and the prospects for thisindustry. Among the planes(2) at the show, a light jet caught Jeff's attentionimmediately. To me it was just a nice elegant blue-and-white jet, but Jeff's description wasmuch more(3). He said that it was a single-pilot jet with two engines, which has anautomated cockpit and can five or six passengers. He also said that the jet is a verynoticeable(4) in air craft construction for years and it may have a wide application invery different spheres. Its non-disputable(5) is that it can land on a runway muchshorter than a runway required by the smallest jet now being flown. Jeff even predicted that the new jet would be used as an air taxi. And he may be right-in the near future business people can be attracted to these jets because they will get where they need to go much faster and cheaper than on a charted business jet. The official at the show said that unfortunately the jets cannot be delivered to the customers immediately assome technical(6) still need to be resolved. After the show I was wondering if that jetcould become an attractive(7) to daily commuting one day
