Cool app... But ...

Really a cool app if its working properly. I use an iPhone 4S, and I constantly have to adjust the compass.
Im in SE Ohio on the WV border, and Im a bit skeptical that Charlotte to Houston flights go over my area, or Tampa to DC. Yesterday it spotted a flight from Los Angeles bound for San Francisco... REALLY??? ;-)
So Im curious about the authenticity of it... But its still cool!
