According to the game's code, the Dodo in GTA III is actually a "car" that has been modified to fly (in default.ide, the Dodo's type is set to car, not plane). This is why it has many car-like properties, such as its resilience to high-speed crashes and car-like behavior on the ground. As well the Dodo in GTA III is the only plane in the entire Grand Theft Auto series to feature brakes; these can be applied by using the handbrake key.
