When we aren't ready for it.
Actually, absent better sauce than you've brought here- it is.
Spatial disorientation is real, and deadly. I demonstrated its effects to every pilot I trained to fly in a visual environment.
Absent better proof- JFL jr died of a "graveyard spiral" into the ocean. He lost visual reference, and while the airplane was turning it induced a feeling in his ears that the nose was falling. The instinct was to pull up on the nose- which only tightens the spiral and increases rate of descent.
Very sad, but preventable accident.
He wasn't. He had some hours under the hood, but was not rated , and did not file an IFR flight plan.
Well, the results speak for themselves. Absent better sauce- your theory remains low IQ.
"special issues" ??? WTF are you speaking of? He didn't have "IFR" training. TO become a private pilot, which he was, you must spend a very small amount of time in simulated instrument conditions. Less than an hour of flight time in most cases. He was not even close to IFR trained, or certified.
He was like most guys with too much money and not enough sense. He was in a hurry, overconfident for his skill level, and paid the ultimate price. Not the first, and certainly not the last.
Night time is not instrument time unless it's under the hood. Graveyard spiral is a very high G maneuver. G load increases substantially as the spiral tightens. No ones hair would be "floating".
Exactly how you get killed. Glad you're not sharing the skies with me, except in your dreams or through your pipe. Have a good evening.
