They’re saying no mechanical or design flaws since it sounds like one of the pilots cut off the fuel, but in the voice recording both are denying having cut off the fuel, so it still has me wondering how they were able to (apparently) accidentally shut off the fuel during the ascent.
Yeah, it isn’t a very satisfying resolution. Whether switched off accidentally or intentionally, why do both deny doing it in the recording? Also, during the time spent resetting the switches, I would imagine there was more conversation that has not been released. The limited information we have may be making the situation seem more bizarre than it is, but I don’t find the current interpretation very reassuring.
Well, it is only a preliminary report. All it seems to be giving us, though, is what happened. The “why” is probably going to be much harder.
