In flight: See the planes in the sky right now ? Interactive

See the planes in the sky right now – Interactive Also charts the history of aviation since 1914.

Food for thought...

Very good -
In use http://www.planefinder.net and http://www.shipfinder.co
for rail you can use http://www.railradar.trainenquiry.com (live rail activity in India)
still looking for a US live rail map but havent found one so far.

I think the www.planefinder.net is not correct ... India does not show a single flight at this moment !

Being the geek I admittedly am, I have the app Flightradar24 on my (android) phone. I am certain it is available for iThings too.

Planefinder works only for commercial scheduled flights in general, although some smaller craft also show on occasion. No military or helicopter flights.
I like the tab where you can view emergencies (under the database tab). I have also used Flightradar, and for satellites you can use www.n2yo.com

Plane Finder is available for iPhone and Android, a free version and paid version (much more info.

Also entertaining is Ship Finder on iPhone.

Amazing to see how many commercial planes are in the air at any time.

Definitely the best. Especially since you can jump into their cockpit and get all sorts of extra information about the actual plane. My kids love this.

Good article. I will be facing a few of these issues as well..
