There is a place where you can rent helicopters. When Niko gets there, a man in a yellow jacket approaches him, and asks if he wants to view the city from above. Instead of replying nicely, Niko blows the guys brains out, and steals a helicopter. The Rockstar Games representatives told the previewer the following: "Congratulations! You're the first of all journalists to fly a helicopter in GTA IV! We actually never thought that any of you would come up with the idea to do that!"
According to the previewer, you can fly the helicopter very high above Liberty City.
The last thing the previewer did was to land the helicopter on top of the GetaLife building, stand on the 'G' in GetaLife, and snipe people on the ground.
