You don't need to be very hi-tech for fs-recorder.......you just turn it on to record a flight (in your extra) do your routine and end the flight. reset the flight to where you started and press replay of the previous flight. and presto there you are on the runway with a recording of your last flight that is about to start. When your alter ego starts down the runway hit the throttle and chase after him(you)...........whole new meaning to the phrase "chasing your tail"

I think you could do it again the same way and get two planes on the runway making you (the real you) as number three.
Staying in formation like this is WAY harder than figuring out FS recorder ;) try it you'll be surprised how easy the program is
