Was the Saturn V safe?
While the Saturn V was a complex machine, the rocket had a remarkable safety record. The Saturn V successfully flew 13 times, including 10 times with people on board. While some of these launches had flaws, in almost every case, the Saturn V sent its cargo safely into orbit.
How many space shuttles have crashed?

Why did the Space Shuttle not have a survivable abort?
The Shuttle program’s goal of returning its crew to Earth safely conflicted with the goal of a rapid and inexpensive payload launch. Furthermore, because in many cases there were no survivable abort modes, many pieces of hardware had to function perfectly and so required careful inspection before each flight.
What is the difference between the SLS and Saturn V rockets?
