Previous media reports (from supposedly well-placed sources) talked about ‘voltage spikes’, ‘rapid power disruptions’, ‘faulty power-panel components’ and ‘EEC glitches’ inferring an uncommanded electronic state change in the fuel switches. This report sadly seems to reverse the causality.

Not only that but if it was an action slip it wouldn\x92t have been BOTH cutoffs one second apart. Clutching at straws indeed.

Action slip seems highly unlikely to me. Even if one cutoff switch was moved in response to a gear up request I can\x92t believe anyone would then move a second switch, one second later.

On two independent switches within approximately one second of each other, which then go back to run again in a similarly human-esque timescale? I just don\x92t see it. It\x92s a duck.

Taxi back out..same same ..back to the gate .,after around an hour they discovered a loose contact at the back of tge circuit breaker panel. This was before SR111 was destroyed in a fire in the overhead panel.
Had a mate have a fire in the emergency busbar overhead panel in a MD80.
Also had two lots of smoke which was traced to the landing light switches.
Two years ago I smelt electrical burning in my hall..soent two days smelling the back of the fridge and eventually opened the cupboard with the fuse box to find a melted circuit breaker caused by a loose contact in the power supply..the earth trip wouldn't have sensed it.
you never know
One loose contact at the back of the breaker panel or two? One melted circuit breaker in the consumer unit or two? Can we not just think about what we\x92re saying here. There were TWO switches. Both still worked after being cutoff.
