Wasn't there a QF B707 upset over India one night during the 1970's? That would have come close to a disaster, I would think.
Yep, VH-EBB, later sold to the Kiwi's.
Story I heard was that the Captain's AI toppled and he followed it, doing a rough barrel-roll but with a few G's. One of the crew managed to crawl forwards and stop it all. Something like that, don't quote me but the rego is right
AFAIK.
