What stands out is this is the 2nd program that I have recently run across which allows for "formation flights" created on-the-fly.
Granted this is/both programs are for FSX only, but I have to say, this "Feature" may be "the future" for FSv-whatever ai-programming.Local aircraft and formations can take-off, fly patterns around the local airport, and land.
Enroute aircraft and formations can follow flight plan waypoints.
Formations of up to six aircraft can follow the user's aircraft
I haven't bought this and am not recommending it. Just thought others might like to know about it. If I do get it, I will definitely report back here - but it's not high on my list - for now, at least.
