Switching ac/ sides commands

[NedLynch]

I think this will work, not sure if there is a different solution:

In flight pause the game, right click on the screen, go to view aircraft.
Find the one you would like to take control of,left click on it in the list and press the key/key combination that will let you take control of the aircraft (I think it is alt-F1, but check in the controls setup to confirm).

I'll look for it as well and will post if it is different or if this advice was not correct.
