Northern Air has dozens of flights daily into and out of Belleville Airport, which is highly congested. NorthernAir depends for its success on economy and quick turnaround and consequently is planning to replace its largeplanes with Skybuses, whose novel aerodynamic design is extremely fuel efficient. The Skybus' fuel efficiency results in both lower fuel costs and reduced time spent refueling.

Which of the following, if true, could present the most serious disadvantage for Northern Air in replacing their large planes with Skybuses?

【选项】The aerodynamic design of the Skybus causes turbulence behind it when taking off that forces other planes on the runway to delay their takeoffs.
