Tracking Flights

Hopefully someone knows the answer to this...

My station is trying to track the flights of someone in a coaching search. We're trying to find the web site other stations are using to track the flights and I've done several searches, but most of them are only showing commercial flights while these are personal/business flights. Any suggestions for a site?

Thanks!

Thanks Webby. Right after I posted this, I found flightaware.com and found one of the plane's we're looking for.

 

also, http://www.faa.gov/aircraft/ will tell you more about the plane being used. you can look up the plane and the owner and all the rest. i always make sure to use the two in tandem
