If there’s one takeaway from the N.T.S.B. statistics, it’s this: flight attendants are in a hazardous business. When planes hit turbulence, the pilots and passengers are usually in their seats. The flight attendants are often still on their feet. They get nearly eighty per cent of the serious injuries caused by turbulence, and, for every one of those injuries, a 2001 study found, another seventy flight attendants get minor injuries. Nearly a third of the time, they have no idea the turbulence is coming.

But human perception isn’t just a passive conveyor belt. It’s heavily top-down. When you imagine an apple (your “mind’s eye”), your brain runs the process in reverse. Your higher-level executive networks and memory centers (the embedding layer) send a signal backward down into your Primary Visual Cortex (V1), forcing those early edge-and-color neurons to fire. You literally simulate the sensory experience. (Fun fact: if this feedback loop is physically missing or disconnected, you have Aphantasia—a complete inability to voluntarily visualize mental imagery [1].)
