This is for a third party app, so it doesn’t belong in #features, it belongs in #thirdparty
I discussed the idea of this a few months ago with @luca1s, the main developer behind Infinite Radar, and he said that Infinite Flight API doesn’t have the capabilities to look at previously flown flights
I believe if this was for Infinite Flight flights, all the routes and data of the flight would have to be cached somewhere online, which would cost a lot of money and require a costly subscription to run.
