At lunchtime on Tuesday, New Yorkers in Lower Manhattan were treated to an unusual sight -- a small plane buzzing by the Standard and Poor's building, towing a banner that read, "Thanks For The Downgrade: You Should All Be Fired."

Commissioned by St. Louis banker and single mother Lucy Nobbe, who paid $895 to hire the pilot, the fly-by was a reaction to the US losing its longtime AAA credit rating last Friday.

"I originally wanted to fly it over Washington, D.C., but learned that you can't do that," said Nobbe. "So I chose Wall Street instead, but didn't specifically intend it to fly over S&P. I'm just a mother from St. Louis who feels the only reason we got downgraded was people in politics. I thought [it was] something that I could do that wouldn't cost a million dollars and maybe someone would listen to me."

Watch as she tells her story to St. Louis news station KSDK:
