Not quite an identical profile; it's not quite 1g, since Venus is less massive, and you're already quite a ways off the surface.

It's still not trivial, but it's not like there are a whole lot of do-overs when launching valuable human cargo from Earth, either. (What happens if the space shuttle's engines go awry? Everyone on board dies, and everyone on the ground speculates as to whether they died within 30 seconds, or survived to hit the ocean.)



The shuttle was an outlier, a rocket without an escape mechanism once the crude, firework-like boosters were lit, which relied on ultra-advanced, brittle and damageable heat shielding for re-entry because it had wings.


The space shuttle was unusual in this regard; Apollo had a launch escape system and IIRC so did its predecessors.
