Re: Poor Design
Err, no.
It was a combination of the tyre blowing out (due to a strip of metal on the runway) and sending one of the biggest chunks of rubber up into an area of the fuel tank, rupturing it after the time where a launch could have been aborted.
so your "Completely ignored safety concerns" were actually a combination of four things - The strip of metal leading to the tyre shred which lead to the ruptured fuel tank at a point where stopping was impossible.
The solution from the aircraft investigators was merely to add extra reinforcement to the underside of that fuel tank in case this massively unlikely event occured again.
