How to build a 3D flight tracker in the browser

TL;DR of how it works:

- Collect some radar samples of aircraft (latitude/longitude/height).

- Here we're using samples of a particular flight from SF to Copenhagen from FlightRadar24.

- Use CesiumJS to reconstruct the path on 3D globe.

- Add satellite imagery, global 3D terrain, and 3D buildings for context.

- These can be from any source/standard format. This tutorial is loading these from Cesium ion.

You can get the raw radar samples from FlightRadar24 in step 3 if you want to try your hand at visualizing this in other ways.
