This site is Awsome and extreamly resourcful!
Earlier today i say an unusual flight and searched all the flight tracker sites to identify the flight, but none were as extensive and explorable as this site is.
I did find the Flight after 15 mins on this site after hours of trying to find site such as this.
Heres a link to a site explaining what I saw and how i figured out what the flight was all about.

Thanx FightAware!
FlightAware is great for helping out with determining the origin & destination of particular flights.
Now they just need to make a web site like this for lost socks…

Omega, how did you add that red dot to the map to show your work location? I like that.
Also, if you look again at http://flightaware.com/live/flight/XNA10. you’ll conclude that XNA10 was originally diverted from KSCK to KSFO and held there for about 3 hours before completing its flight.
It could be there was an airport problem at KSCK. It could be there was a flight situation where they wanted to land on a longer runway. It could be they had a maintenance problem that could be better handled at KSFO.
I just thought you’d like some more stuff to research.

the odd thing though is that it flew to stockton 14 days ago at about 12pm
There are some interesting deviations from the standard KDAY/KSCK routing of XNA10. For instance, on 12/23 the flight originated from KECA, which FA does not recognize as a valid airport code.
A quick Google of [ECA airport] returns Emmet County Airport, East Tawas, MI. Is that an airport that handles Airbus 300s?
Some things we might see here are beyond understanding, but not beyond wonder. 
i thought the same thing when i saw it fly overhead bound for stockton, but then again it was a ferry flight possible maintaince or just getting logistics right. there is a big port in stockton possibly why it does flights out of there, though i thought SCK could only hand 727,737,a320 and other narrow bodies, guess im wrong time to start spotting!
The only airport in East Tawas, MI is Iosco County airport., 6D9. Its only runway is 4800 feet and it doesn’t have Jet-A. I kinda doubt an Airbus would use that airport. When I ask www.airnav.com (a great site for finding airport information, by the way) about ECA it redirects me to 6D9, making me believe that once upon a time its identifier was ECA and that it was changed.
As of today, there is no airport ECA. However, there is a VORTAC ECA, Manteca, which is just southeast of the Stockton airport. Is it possible that the flight originated from Stockton (like most of the XNA10 flights seem to do) as a VFR flight, then picked up its IFR clearance over ECA VOR, and the controller entered it as KECA instead?
