I guess Takei will want to go up next.
Only if he gets to go higher than Shatner, of course.
I think it would be a nice touch if they all wore comm badges. Or if the spacesuits were mustard (mustard for Bill, the rest can have red - stuff 'em).
Trek fans - "He's wearing a TNG comm badge. The canon!"
Can they give the rocket a temp. registry of NCC-1701?
Anyhoo ... no doubt, there'll be something Trek-related. Knock it out of the ballpark, Bill. You might inspire Bezos to buy the franchise from the creatively bankrupt Paramount!
