@farmerman,
I was able to see the approaching shadow. Conditions were such that the temperature drop caused a light ground fog to form as the totality approached. I was well above the haze at 14,500 feet but it made the shadow line on the ground less clear but you could definitely see it coming. It moved
really fast.r
The guy on the radio was right. Totality is the real show. There is something surreal and indescribable about it. Your eyes are drawn to this black hole in the sky surrounded by a light that redefines the term 'contrast'. I couldn't look away. I have no idea what the surrounding sky looked like, never saw the stars come out that I'm sure were there. The corona was very obvious and beautiful but I did not see the 'ring of diamonds' effect that I've heard about. I wonder if that's what you see if you keep the goofy glasses on? Naked eye is the only way to go during totality. Before and after I was amazed at how bright it was with only 10% of sun showing.
If I were to do it over I'd leave all the cameras at home not waste a second trying to photograph it. It's a waste of time no matter how good they come out. Just take it in.
A lot of other pilots had the same plan. There were over 50 airplanes within 10 miles of me at totality, and that was just the ones equipped with ADS-B out transponders that I could track. Never saw them though, most of them were well below me where you don't need supplemental oxygen.
Well worth burning 30 gallons of Dino juice to see.
