Spy Infiltration

You jump in the rusted pilots seat. You try to take off, but all of the controls are in English, foreign to your natural Russian language. Feeling clueless, you press a few random buttons and the engine starts. Such Luck! You take off while barely flying over a building. When the police below catch sight of you flying low, they pull out an RPG and aim it at your heli. You here a loud bang and see the missile from the RPG coming towards you.You dont have much time. Do you jump out without a parachute and try to land on the roof that is not to far away, or do you stay in the heli and hope for the best?
