Ad in the bottom left covers the UI when expanding the menu out.

I'm sure it depends on screen resolution etc but I'd love to be able to click links to the data sources.

Overall an interesting idea. I'd love to know the data source for the cost of the operation of the aircraft. Would be really interesting to connect a database of all aircraft types then present the ability to watch the cost of like "all American Airlines flights currently flying" or "all US military aircraft".

sorry probably got covered by the ad - data source is the hourly from the city controller https://controller.lacity.gov/landings/lapd-helicopters which says $2,916 per flight hour
