I know that this app on iphone and this web can show airtraffic. There is one thing it can't do.

Tell the truth as such information can be potential aim of terrorism.

This is very interesting :) i can now see where my girlfriend is when she is on a flight :D

wow this is so cool. It's interesting to search up planes that you've previously flown on and see where they're headed now

 plane based website i read:

http://avherald.com/

if you dont like flying it maybe best to avoid looking at it though!

Both of these are very interesting.
