Last Saturday I was at an air show with a friend. Jeff, my friend, is considering a career in aircraft ____(1) and that’s why he is interested in aviation and the prospects for this industry.

Among the planes _____(2) at the show, a light jet caught Jeff’s attention immediately.

To me it was just a nice elegant blue-and-white jet, but Jeff’s description was much more _______(3). He said  that it was a single-pilot jet with two engines, which has an automated cockpit and can carry five or six passengers. 

He also said that the jet is a very noticeable ______(4) in aircraft construction for years and it may have a wide application in very different spheres.

 Its none-disputable ______(5) is that it can land on a runway much shorter 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 as some technical ________(6) still need to be resolved.

After the show I was wondering if that jet could become an attractive ________(7) to daily commuting one day!
