The first thing that came to my mind was sonic boom, which made me think of Guile from Street Fighter II, who was one of my favourite characters. It also reminded me of my dad describing the sound of sonic booms as jets passed overhead (he lived fairly close to an air force base).
Then I read more comments here and now I think of crashing and death :-(.
In the previous thread some associated "Boom" with "Something blowing up" which wasn't perceived as a great name for a plane.
Yeah, I thought it was a horrible name in light of the fact that the last supersonic jet program was permanently grounded because of a crash.
