Didn't I read somewhere (or is it just an FS urban legend?) that the Comet was supposed to be part of the default aircraft in FS9 after someone mentioned it being quite a famous plane (being the first jetliner) but someone at MS tasked to find out and knowing little about these things looked up de Havilland Comet and found the DH88 racer which in it's time was famous as well, so they made that instead.

hahah...well, americans!
The Comet4 was the first passenger jet, and americans like to "forget" that fact...pretty much like they wish to remember John Glenn, despite Gagarin was the first man in space. :)

My Dad was a Comet4 Captain and flew transatlantic flights from South America to Europe in the 60s
