 The aircraft has limited fuel (though a fuel tank can be added at the weapon selection screen for more fuel to allow for a longer time to complete the mission) .If the aircraft being piloted is destroyed by enemy fire, crashes into the sea or runs out of fuel, the pilot survives but the plane being piloted is crashed and unable to be flown again at any further point in the game, so in essence, the player has three lives throughout the game.Three aircraft are available to pilot within the game
