A week and a half ago, the San Francisco 49ers Week 12 home matchup with the Arizona Cardinals was preceded by an amusing banner flying over Levi's Stadium. A GoFundMe was set up to finance a banner suggesting Jed York and the 49ers should "mutually part ways". It did not last for very long due to the cost of flying it around, but it got local media attention.
It turns out the folks at Levi's Stadium took notice of it. Ryan Sakamoto of NinerFans.com was able to put together this video with audio between California Highway Patrol and the air traffic control tower at the nearby airport.
