The Flight Framework is an ActionScript 3.0-based framework for building applications in Flash and Flex. The code is hosted at Google Code as an opensource library under the MIT License.
To get started download or checkout the code and add it to your project. Be sure to read through the documentation (as available) to become acquainted with the methods and best practices of the framework.
The Flight Framework is developed and maintained in a subversion repository as a Flex Library project. The Flex Builder project files are also versioned for convenient importing into Flex Builder 3. The project source is hosted on Google Code. The trunk of the repository contains the latest build and is often the least tested. Stable builds are tagged first as a Release Candidate (rc) and later as a dot release.
The project is also available via download and includes both source files and the SWC (compressed library). By downloading the SWC and adding it to the library path of your Flex application you will have full access to all of the Flight Framework classes. You can also reference the entire library inside Flex Builder for convenient access of Flight’s source code.
