So then we'd have to assume that the error was not a 'simple' one. Which is a lot harder to find and fix, almost by definition.
I mean, look, this isn't a good sign for spacex. Whatever problem there is, clearly it's hard to find and fix. Could be some alloy, could be some pressure sensor, could be the whole management chain. Who knows yet.
But we very much do know this isn't a good sign.
