Purpose
Firehose is a FlightAware API for receiving streaming flight
positions (e.g., Radar, ADS-B, Mode S multilateration (MLAT), datalink, etc) as well as flight status
data (e.g., flight plans, departure/arrival messages, flight updates) and surface movement positions.
This page defines a protocol for establishing a connection and receiving data from the Firehose
interface.
