I have a friend who studied aerospace engineering and he told me that the space shuttle was engineered to have a critical failure on average about 2% of the time. And guess what? The Challenger was destroyed on about the 50th mission. I wonder how many missions had been flown since the Challenger...
The fact is, with current technology we just cannot make this 100% safe. The materials are too volatile, the temperatures too hot, etc. Most of the cost already goes into safety engineering. If the shuttles were engineered for lower tolerances they would actually cost lower overall, albeit at the cost of more deaths.
I bring this up because my friend told me this information during an amusing anecdote: the professor asked the class of aerospace students how many student would be willing to go on a flight if they though there was a 10% chance of blowing up. Most of the class raised their hand. Then he went up - 15%, 20%, 25%, 30%. Almost half the class was willing to go on a flight that would explode one out of three times!!!! Crazy 😱
