Loose lips sinks ships!
Never use country channel for comms. After the mission has enough players only use mission channel, (but if you have a spy IN your mission nothing helps). If possible change starting location and other mission parameters just before launch. If you have enough players to spare send a decoy flight of fighters according to the original mission plan to emulate the strike package and lure the enemy interceptors into a trap.
Just a few ideas...
