What is the cheat of the rhino tank fly in the air in GTA 3?

To make the tank fly, just input the tank cheat (or get in a tank if you already have one), which is giveusatank on PC or 'Circle,Circle,Circle,Circle,Circle,Circle,R1,L2,L1,Triangle,Circle,Triangle' on PS2. Then input the Dodo car cheat, which is chittychittybb on PC or Right,R2,Circle,R1,L2,Down,L1,R1 on PS2. Find a nice long clear and smooth stretch of road (I recommend the runways at Francis International) and point the cannon behind you. Accelerate forward and as you build up speed, release the accelerator and shoot the cannon continuously. This will give you forward momentum and you will lift off the ground. DO NOT STOP SHOOTING THE CANNON. If you do, you will plunge downward and crash. Unless there's water there or you land upside down you will be fine anyway because it's a tank, but you don't want to have to travel back to the airport and all that again.
