Flightaware.com

Just wanted to let you know....
There's a website called flightaware.com that's pretty cool. 
If you need to track someone's flight coming in to town
and you're not quite sure when they will arrive, or when to leave the house
to go pick them up this is invaluable.
All you need is their flight number and the airline they are flying on.
You put that info into the blanks and they will give you when they should arrive,
when they took off, current wind speed, altitude, miles flown, miles to go, what gate
they are expected to arrive at and all sorts of useful information including delays and
weather.  You even get to watch the map as the plane travels across the country or world.
Try it out when you get a chance.  I love it and use it all the time.
