Exhibit: Sabres over Korea
" NOTE: When flying these, or any other CFS Missions, you'll probably get used to
seeing a blue text message that regularly pops up and says "Press X to skip to
next action sequence". Some people think that this is an order. It is not an order.
It is, unfortunately, an obligatory message from Microsoft that cannot be completely be removed from the mission script without causing other more serious problems. None of these missions require that you comply with that instruction, so please ignore it.
If you want to press X to warp through the waypoints to an action sequence, then that is an option that you can choose, but unlike the message, it is not obligatory.
Warning: Some Missions may play differently than intended if you do warp at the beginning of the mission. "
