landing in a Citation 550 on runway 4R at Chicago Midway airport. Midway is basically a one mile by one mile square set in a heavily populated area south of Chicago. All of the runways have displaced thresholds due to the close proximity of buildings. KMDW is one of the world’s busiest general aviation airports. It’s a hub for Southwest airlines and the FBO’s serve hundreds of corporate jets and private air planes on a daily basis. This Cessna Citation II is landing on runway four right. Of interest is how close houses are to the ends of the runway.
