Our house shook. I’m sure it’s a rocket launch but never felt our house shake and ears ring from a launch. Felt like a helicopter sound except, surround sound. Like the whole earth. Then 2 minutes in it dies off and then boom. I’m so confused.

Yes
Remarks
It sounded like a helicopter on surround sound and then it faded, then we felt and heard a sudden boom.
