An auto throttle failure in the UK and the Asiana crash at SFO. Hard to count the Asiana crash against Boeing. A day, 12 mile visual straight in, CAVU weather is something even Asiana’s pilots should be able to handle.

I thought the UK crash was due to ice in the fuel system. And Boeing didn’t make it out of the Asiana crash investigation unscathed:
Contributing to the accident were (1) the complexities of the autothrottle and autopilot flight director systems that were inadequately described in Boeing’s documentation...
Bad on Boeing for not making the autothrottle system idiot proof.
