Southwest jet narrowly avoids colliding with business jet at Chicago airport

A Southwest Airlines flight was forced to abort a landing at Chicago Midway airport on Tuesday and narrowly avoided a collision with a business jet that entered the runway without authorization, the Federal Aviation Administration said. Around 8:50 a.m. CT, Southwest Flight 2504, a Boeing 737-800 arriving from Omaha, Nebraska, abruptly pulled up and flew over a FlexJet Challenger on the runway. The Southwest plane performed a go-around, a maneuver in which it circled and reapproached the landing.
