No, and there had already been an accident with this very core. https://en.wikipedia.org/wiki/Harry_K._Daghlian_Jr. Sadly, there was no good reason for this, just a young cocky guy. Not a bad man, and we've all made stupid choices, but his sadly was a bit historically significant.
I like the adage,
"We all start with a bag of luck, filled, and a bag of experience, empty.
The trick is to fill your bag of experience up before your bag of luck runs out -- ie. when your bag of luck runs out, you die. Most people have a couple events in their life where they almost died -- of course we know we should have never made those choices -- but its easier said now that we have the experience knowing we got "lucky." :-)
I've never heard it put that way, but I've had this conversation with friends before, "Hey, remember when we almost died doing 'X'?" You're right, absolutely right.
