Actually you can remove the pilots from the plane but you fly completly without them
Go to the file flightsimulator.cfg located in appdata > local > packages > microsoftflightsimulator_8wekyb3d8bbwe > localcache folders for pc xbox for steam it maybe different.
And open the file up.
Now look for the line " [Graphics] " when you found it look for the line underneatth which says the text,
“See Self=1” change here the 1 into 0 and save.
Start up the sim and now you have your selected plane with no pilots there.
I suppose that if you do it like this and replay recorded videos you may find your plane without any pilot.
Good luck
