Flight was created at Twitter by Angus Croll, Dan Webb, and Kenneth Kufluk, along with other members of the Twitter Web Core team. A full list of the team involved in the development of the open source project is available on Flight's GitHub page at https://github.com/flightjs/flight.
Flight was created to provide a reliable, extensible framework for web applications, specifically to address performance and maintenance issues on the twitter.com website.
It is designed to obviate the need for a rigid model or view and the boilerplate that entails, allowing rapid development without sacrificing maintainability.
