SpaceX Starship explosion likely caused by propellant leak, Elon Musk says

"Preliminary indication is that we had an oxygen/fuel leak in the cavity above the ship engine firewall that was large enough to build pressure in excess of the vent capacity."

It’s their 7th launch and they’re still fighting issues with keeping the fuel where it should be. Elon has successfully created a machine that can kill any number of astronauts in sub-orbit and land to do it all over again. How is anyone not getting this? I’ll never forgive him for taking back intellect on space travel to the 1950’s .
