Successfully complete the game and save when prompted. Use that saved game to continue and choose a mission. Press Square at the aircraft selection screen to choose from the Vic-Viper or MX5000.

Easy money
To earn double money, kill enemies using the machine gun (not missiles or bombs). You can use those weapons to damage enemies, but the last hit must be delivered by the machine gun. Some air enemies will give more than double the money. When you finish the mission you will see the scoreboard, showing the enemies you killed with the machine gun with double of the money than normally awarded.
