A Boeing 787 was coming in to land at London's Heathrow Airport last week during a winter storm. It got caught by turbulence (possibly wind shear) during the last few feet of its descent, and almost went out of control. Full marks to the pilots for getting out of that mess.
A brown-trouser moment for sure, to the observers. I'm not sure whether the passengers realized what a close call they'd had. Kudos to the flight crew for their quick reactions.
