Yahoo Maps provides a component that you can use in your Flash and Flex applications. FlightAware provides an API (you have to pay, not free) that allows you to get tracking information about air traffic. Together, you get a mashup of tracking the progress of an airplane currently in flight over the USA via an animated map.
This example shows how to get dynamic data onto a YahooMap component from FlightAware’s DirectFlight API using Flash 8, AS2, and PHP. PHP converts FlightAware’s XML to a smaller, more Flash friendly, JSON format.
