On the enrollment enter your name as "CIARAN" then load up the pilots log. THE NAME SHOULD NOW READ {OCEAN OK}. NOW You can fly any mission with the huge benefit of infinite missiles and cannons.
Also, choose "THE DIDDY MEN" for your name, click {COLONEL} icon and hit 'RETURN'. Accept a mission (without selecting one) then go back and select a mission. Now start the game and play as normal. Hit 'ENTER' to automatically land the plane.
