I take a 30 to 40 minute walk (2 miles) every day at work. Sometimes it's to clear my head. Sometimes it's to think about work. Sometimes it's to think about not work. No one cares, and if they did, I'd argue it's time well spent for the company. I can't get anything done if my brain is overflowing with crap.
Man, a work LAN party would be pretty cool.
It's not hard to imagine. Spacial Disorientation is where your brain can't tell the difference between acceleration and climbing very sharply. It happens when there's no visual references. It sounds like the flight was dealing with overcast weather, so there might not have been a true horizon.
It's happened before. Atlas Air Flight 3591. United Airlines Flight 1722. Flight 1722
