The "flight" plugin to Beyond411 gives access to a flight tracker, listing knots, altitude, ETA, etc. You might try that out. I have used it before and really liked it.
I bookmarked the link above.
There was some other good wap sites in this area that I lost if someone is able to post.
I am not interested in flighttracker.com or flightstatus.com which gives you orbitz and cheap tickets

23 to GO Home is a news channel, but they have a link to track flights. I have used this many times before, it is updated in real time, and works well.
