Not according to wiki, but LockheedMartin and Boeing do have joint ventures, maybe thats what you're thinking of. Anyways, I was going to say McDonnell Douglas, but they actually were merged into Boeing years ago.
Speaking of logos, I saw someone had beat you to a MS Windows logo, but its kind of an older version of the logo anyway.
As for suggestions, how about Firaxis's fire wheel or black hole (or whatever they call it) logo.
