Wow! Have you heard of the "Knee Defender?" It's apparently a real gadget you can  buy for $22 that stops the person in front of you from reclining. That's what a 48-year-old male passenger tried to use on Sunday, on United Airlines Flight 1462 from Newark, New Jersey, to Denver.

It bothered the female passenger in front of him so much that she asked a flight attendant to ask him to stop using the product. He refused. The female passenger then threw water on him and a giant fight ensued! The plane had to make an emergency landing shortly after in Chicago, where both passengers were met by police and not allowed to continue on to Denver. Do you think any of this was fair? What bothers YOU on a plane?
