Live flight position (OpenSky) API

Looks up an aircraft by callsign or ICAO24 hex on the keyless OpenSky Network and normalizes its raw positional-array state vector into a clean record: live latitude/longitude, barometric & geometric altitude (with feet), ground speed (with knots), heading and compass direction, vertical rate, squawk, origin country and on-ground flag. The value-add: parsing OpenSky's untyped index-based array format an LLM can't reliably decode. Answers 'where is flight X', 'live position of this aircraft', 'altitude and speed of this callsign', 'is this plane on the ground'.
