I need video+audio of a rocket or space shuttle taking off. The audio
needs to include the full booming rumbling of the rocket taking off.
It must be a USA launch and a successful launch but can be any spacecraft.

Hello shikibobo and thank you for your question.

Please find below several websites where you can find video+sound
movies of US rocket launches.
