In case you've somehow forgotten, United Airlines is having a horrible year. From leggings-gate and in-flight animal deaths to the infamous violent removal of a passenger from an overbooked flight, the airline has found itself in the midst of some serious controversy. And just when it seemed like things couldn't possibly get any worse, they did. United is now under fire after a video showing an employee pushing a 71-year-old passenger to the floor in an airport was brought to light in a Harris County, Texas, lawsuit filed last week. The footage is two years old, but was broadcast to the public on Tuesday by KPRC, a Houston news station.
