Astronaut deaths: shuttle versus other accidental deaths

I see all the talk about the risk of flying the shuttle and it makes
me wonder. 14 astronauts have died in shuttle accidents. Over the same
time period, how many astronauts have died from other accidental
causes such as car or aircraft crashes ?

A lot of professions are risky. Is the shuttle flight risk that much
more than say building a highrise, working on microwave/radio towers,
etc. ?
