An interesting game. The only winning move is not to play.

I loved having hundreds of c64 games with no manuals. So with this one, we thought you needed to fly the plane out the only visible door in the hangar, which was the one the pilot comes in through, and it was barely bigger than the plane. Seemed impossible to line up. Not like you could look things up back then, and if you were lucky enough to know some friends who played it, they'd often have the same issue. Can't get out of the bloody hangar. Then one day, one of my brothers puts his feet up on the computer desk and kicks the F7 key on the bottom right of the keyboard while I'm flying the plane around the hangar, and the wall opens up. Well, shit. From there, it was pretty fun to make the Zaxxon-like run to the Kremlin and then pick it apart with your RPGs. Lots of good memories of this one.
Applications such as Exchange/Outlook turn a double dash to an em dash when you type it. I've used them for a couple decades.
