No.

You have to do missions if you want a new one
I believe there are 94 main missions in grand theft auto IV, but there are many side missions, with secondary characters, and extra jobs, etc.

You do not say which game you are playing. Is it GTA IV or GTA San Andreas, or another of the GTA games?
There are 94 missions on GTA IV. For a complete list of these missions look in the related links section.
depends what mission you are on now
I would say GTA IV because there are many awesome crime missions such as bank robberies gang fights and cops all over the place.So if you liked ANY other GTA game GTA IV is the best game for you.Plus it has online multiplayer
i don`t know but i think you have to steal a swat car or truck and for pc you press e thats all i know also there is another answer on GTA IV but i don`t know the title I hope this helped
94 MissionsThere is actually 94 missions without taking into account the side missions.
You do not say which of the helicopter missions in GTA IV. But, if it is of any help: All of the helicopter missions on GTA IV are helped enormously by helicopter flying practice. It is worth jacking one of the Maverick helicopters from Helitours in Algonquin and practising taking off, flying, and landing, regularly, until you are able to do this easily. You can then approach the chopper missions with more "flying" expertise.
