This model of the plane ICARUS (ICARUS is a seaplane) carries with it a guided missle. activate the group 1 to turn on the plane's engine, activate the group 2 to activate the rotation of the backside lnding gears, activate the group 3 to turn on the missle's engine, activate the group 4 to detach the missle. After the detaching of the missle you can still controll it thanks to an orbit camer located on it. I suggest to lunch the missle while the plane is flying over the sea because after lunching the missle you can turn off the plane's engine and focus on piloting the missle (don't worry when you turn off the plane's engine because it will utomatically land into the sea). On the missle is also located a camera. The missle can also float in the water.
