About Airframes
Airframes is an aircraft-related aggregation service that receives ACARS, VDL, HFDL, and SATCOM data from volunteers around the world.
It is under very active development and you will notice changes from day to day. Also, issues are expected.
Contributing your feed allows us to make ground developing new decoders and make important statistical observations. It also benefits users of the service so that they can see more about flights as they traverse covered territories.
