Spent some time last week reading the linked pdf of the AAIB report
BBC News - Missing rivet head 'caused Farnborough jet crash'
I struggle to understand what happened - looks like there was an associated vibration that caused the pilots to shut down one engine, then the second engine was accidentally shut down possibly because of a missing rivet head, when they only intended to reduce its speed.
Would a pilot really shut down an engine totally because of suspected vibration without being 100% sure? Sounds sadly like a repeat of the BMI crash on the A1 from the ? 1980's ?
