I think you misunderstood my question. The page you linked allows a user to enter a specific aircraft type…a 172, for example…and view all airborne 172s.
I would like to view a complete list of ALL aircraft types in the air at any given moment.
For example, there may be 100 757s aloft right now, but there would only be one line for “B757”. Clicking “B757” would take you to the page where you can view all the individual 757 flights in the air.
This way, users could scan down the list and notice if, for example, an Antonov or Illyushin was making a visit to the States.
EDIT - Exactly, Mduell! Man, browsing through that list, I notice there have been AN-24s, AN-26s, DHC-7s, IL-62s, IL-96s, Spitfires, and other rare, interesting types flying around. It would be great to be able to browse through the list of active types, and spot an interesting type in my neighborhood. To the airport I would go!
