If the name of one of the companies making the concorde was Boom, I'm very sure people would know it.

In fairness to the public, the two companies involved in producing Concorde have each changed names 3+ times after merging with other major aircraft and industrial concerns, and are each now fading memories as part of the two largest European aerospace & defense conglomerates.

I'd actually wager a significant portion of the population would correctly say Airbus, but for the wrong reasons - it's the only French aerospace company they can think of.

I did a straw poll among some friends and got a lot of "I don't know what that is. Do you mean the grape?"
