Shortly before the challenger disaster Thiokol engineers warned, that the O-ring that ultimately failed wasn't tested for the occurring low temperatures and would likely fail, but NASA went forward with the launch anyway because is had been delayed multiple times already.

Do you think NASA was too reckless because they had so much success in the past and felt "invincible"?
