Was he doing loops/flips intentionally, or did he lose control of the plane? Either way, what an absolute legend to be flying solo at his age.
Intentional loop. He entered it too fast and too low. On the descent, he was going too fast for his aircraft to have any type of control authority and he was a passenger at that point. The aircraft basically stalled out in a dive, and with no cohesive airflow over the control surfaces, the aircraft continued to stall to the point of impact.

The shutter speed was 1/250th of a second, so the earth rotated about 4 miles or 6 kms while the shutter was open. Not enough to blur the photo obviously, but crazy to think about.
Circumference is 24,901 - so about 1000 mph at equator.
1000 mph / 3600 s / h = 0.27 mps
0.27 * (1/250) = 0.001 miles?
Doing this math on my phone but am I missing something here?

When you've ridden a Saturn V, the difference between a jet engine and a prop engine becomes immaterial.
Dare I bite: Why?

I’m confused. Does this math check out? Circumference is 24,901 - so about 1000 mph at equator. 1000 mph / 3600 s / h = 0.27 mps 0.27 * (1/250) = 0.001 miles? Doing this math on my phone but am I missing something here?

360/86,400=0.0041667deg/sec
0.0041667 * 0.004sec = 000016667degR
circumference:
2pi * 6371km = 40,030km
land covered by rotation:
40,030 / 360 = 111.194km/deg
0.000016667deg × 111.194 km/degree = 0.001854 km
km to m:
0.001854km × 1,000 meters/km = 1.854 meters
more like 0.001 miles. ... oh, woops. I see your answer is in kms.
it was something like 0.46km/s.

Heh. I'd never read/heard that quote before. But no one's photos have touched me more than Galen Rowell's, so it bears an incredible amount of weight to read.
Thank you for sharing it.

It's an open secret in the aviation community that large numbers of aging boomers are medically unfit to fly but are able to maintain their medicals, for a variety of reasons.
I personally don’t think that people that age should be driving even a car in public. Any time I am stuck behind a car driving slow, eg. doing 30 on a 60, it’s an old person. It’s dangerous, nearly seen so many accidents with people overtaking. But then again, if it’s someone’s own plane and there’s little risk to anyone but themself, then maybe fire in. But wow should the insurance be through the roof.
Since there’s a lot of commenting about his age, I’ll remark (as a 36-year-old private pilot) that in my opinion an elderly man flying recreationally is actually much less hazardous to the general public than an elderly man driving a car. Flying is a specialized skill, but once you learn it it’s not especially difficult and requires less sustained focus, reflexes and reaction time than driving. It’s not as if there’s…
