Trying to isolate a sound

First of this: https://www.sendspace.com/file/3npyir
Is a small demo of what i’m talking about.
I’m rather new to alterning audio, especial audio taken from a video and trying to isolate a certain part.
In this case you hear camera shutters, a bit of a helicopter, and some voices. But the main part that i want is the Rocket lauch sound.
Can anyone help me with removing the camera shutters and other noises

I doubt that you (or anyone) will be very successful with this. I’d suggest that you look for a better sound - freesound.org has a lot of free sound effects.
