What specific phrase has Musk reportedly used when wishing Blue Origin well before the New Glenn launch?

Godspeed.

Despite the ongoing and intense competition between SpaceX and Blue Origin, there are documented instances where Elon Musk has offered public well-wishes following a notable milestone or preparation for a major launch by the rival firm. Specifically, when Blue Origin was preparing for its New Glenn launch, Musk was known to extend congratulations and use the phrase "Godspeed" directed toward Jeff Bezos and the team involved. This gesture exists within the broader context of rivalry, yet it serves as an acknowledgment of the immense technical difficulty inherent in attempting to reach orbit, validating the high engineering barrier to entry in heavy-lift rocketry.
