Is there any rocket-builder without a history of blowing things up?

No. Blowing things up is the reason for rocketry to exist and its historical basis.

Fun fact:

Remember our esteemed national American hero, and spiritual father of SpaceX, Wernher von Braun.

Wernher wrote a book about Mars referring to "The Elon", an imaginary Mars governor, and the father of Elon Musk claimed that Elon's name came from there.
