Ably LHR Arrivals Tracker

This demo app uses live aircraft data for flights due to arrive at London Heathrow. A circle is drawn around Heathrow airspace which you can resize using the appropriate buttons in the menu bar. If a plane enters the circle, the circle flashes and the plane colour turns from blue to red. Click on a plane to see the flight details.

To run it:

1. Copy sample.env to .env and enter your Ably API key secret.
2. Run npm install and then npm start
3. Visit https://localhost:8080 in your browser.
