Mission skip: Hold [Option] and click on "Briefing".
Alternatively, hold [Option] and select "Tour Of Duty"
from the "Pilot" menu. Then, hold [Option] and
click on "Go To Next Mission".
Drive at 4500 mph: Enable the "Invincibility" option. Take off,
but stay on the ground with the landing gear down. Activate the
afterburners to "drive" at over 4500 mph.
Aircraft select: Hold [Option] and select "Tour Of Duty"
from the "Missions" menu. A prompt with two fields for
mission number and aircraft will appear. Enter one of the following
case-sensitive aircraft codes to use that aircraft in the corresponding
mission. Note: In order for this cheat to work, the selected mission
must already contain the aircraft that is chosen. Alternatively,
type fly:<aircraft code>-<aircraft number>
as a call sign. For example fly:MG21-00 or fly:B727-00.
