False flight info

I downloaded this app to track my wifes flight from Chicago to Philadelphia. She texted me to say the flight was delayed a half hour, which in fact it was. However, this app showed that the flight had left on time. It even had the airplane flying happily over Indiana when it hadnt even left yet. Fortunately I had also downloaded the airlines app and that had the correct info.
