Qantas flight tracker

tracker.js

// Got bored on a flight and their tracker was broken, so I spent half an hour writing a tracker
// Relies on Viasat in-flight entertainment system, tested on a Qantas Boeing 737
// Uses geocoding for origin/destination coordinates, but untested and commented cause I hit a ratelimit
