thats interesting, the FAA stopping that.. hmm.
well, the runways ARE enough for the 762, thats for sure. from: http://www.boeing.com/commercial/767family/background.html
With its advanced-design wing and powerful engines, and at a maximum gross weight of 300,000 pounds (136,080 kg), the basic 767-200, can take off on only 5,700 feet (1,735 m) of runway. It can operate nonstop between New York and San Francisco with a two-class load of 224 passengers.
The runway 13C/31C at Midway is approx. 6500 feet long, im not saying that the terminal and ramp area could take it, but the runway can. i just was asking if the terminal gates would be made big enough for it.
