How about:
"Ambiguous 1"
?
It would help if we knew more about the rocket in question, and preferably had a picture to look at.
If it's insanely dangerous, "Running With Scissors" is appropriate.
If it's likely to disappear out of sight and never be found, "Wreckless Abandonment" would be good.
"Positron" would be suitable if it is the kit of that name.
"Apogee Unlimited" would be suitable if it's a kit from the relevant company.
"I Have A Better Name" would be interesting when read out at launch time.
I guessed what you meant, hence the smiley on that suggestion. However, at the moment there are 5 votes for "I Have A Better Name", only 3 actual suggestions of an alternative name, 2 of them from the same person, which implies at least some of the voters actually want the rocket to be called that! (I'm not one of them...)I didn't put "I have a better name!" as a choice for the rocket name, it meant that you don't like any of my names and you think you have a better one. I guess it could be the name if you want it to. Who wants it to be a rocket name?
