What was the first Mass produced Jet Airliner

Hello all,I was just wondering what was the first mass produced Jet airliner to really signal the end of the Props in front line service. I know that the Comet was first in the UK and having structual problems it had a very fatal start,
But what aircraft really made the leap and became the first true Jet flying.
I have always loved the Lockheed L-049 (Connie)In my opinion it was and still is one of the worlds most beautiful aircraft and I was setting here thinking what could of been beter than flying the Connie so it must of been an impressive airplane I just can't think of what it was!
