Flight scheduled while aircraft at wrong location
So, I bought a 757 somewhere in the US. Decided to ferry it to London via Gander. While it was enroute to Gander, I created a route for it (LHR-EWR-LHR), and activated it so I wouldn't forget later. I saw that the two flights appeared in the scheduled flights list and thought nothing of it. Then, when the aircraft landed in Gander, I went to quick flight it to London, but its now marked with the green 'waiting for next flight' symbol and doesn't let me do a quick flight. I assume tomorrow morning it'll fly LHR-EWR and then EWR-LHR (and end up in Heathrow at the end of the day), but how did the route schedule when the aircraft was not in London? Pretty sure this isn't meant to happen...
