Every year there are between 600 and 700 recorded deaths from recreational boating alone (not counting industrial or military accidents) [1]. No matter how safe we make it, there will always be accidents, and those accidents will kill people.

Nothing is perfectly safe, but if you could make space travel as safe as boating then I'd say heliodor was correct.
