Rob is a minor character in Grand Theft Auto IV.
Rob flies for Higgins Helitours. During flights, Rob mentions that he's "seen war zones" and that it is "better flying for fun than to wipe out a village", and given his age, and his piloting experience, it is possible he was a helicopter pilot during the Vietnam War.
The player can enter his helicopter at the Helitours and he can take the player on a number of aerial tours around Liberty City including a tour of the bridges, Algonquin, and Dukes. Higgins' services cost $150.
