I was flying from Honk Kong to Incheon right about 3 years ago today on the upper deck of a 747 in Business.
Looking out the window there was a massive cloud deck with giant circular holes due to a Typhoon blowing through. The pilot was cranking and banking up and down and left and right and turbulence wasn’t too much. Then I hear “flight attendants take your seats...kinda frantic” with lots of bongs.
Holy frijoles fritos! That was the most intense turbulence I’ve ever been in and I’ve got north of 500,000 miles under my belt. Twice the plane was kicked to the right so hard that I bruised my ribs on the left arm rest. I was black and blue for a week. I didn’t blow, but at least half the folks around me were re-serving lunch. There was loud cheering and clapping on that landing and I was glad to get off that vomitorium!
Or maybe they could have been reversing lunch.
Some of my younger crew members used to call it "Calling Ralph on the big white phone".
Seems to be human nature to use the head for something that could have been barfed over the rail.
