When you've ridden a Saturn V, the difference between a jet engine and a prop engine becomes immaterial.
I'd be surprised to see a pilot endorse that

In my opinion Chuck Yeager was the best pilot ever. A World War 2 ace who shot down 13 German planes. First to break the sound barrier. But Yeager took his last flight in a jet at 79 (with a copilot) and surrendered his pilots license at age 80. I am not taking anything away from William Anders but 91 might have been just too old to be responsibly flying a jet.
The T-34 is not a jet.

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.
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?

At a minimum, flight reviews every two years. More applicable to a 90yo is keeping a medical.
For private flying, the medical is a lot less stringent (as I understand it.... I'm not a pilot).
According to the FAA airman registry he was flying on BasicMed (less strict than third class, but comes with loss of certain privileges).

Does a solo plane crash have a statistically smaller chance of hurting anybody else?
Crashes are most common on takeoff and landing, and that means you're over populated areas. GA and military crashes that kill people on the ground happen all the time. Used to happen all the time at airshows, too - until airshows adopted very strict rules around planes never having a trajectory that heads towards the audience. But that's all beside the point. A 90 year old has no business flying a fighter jet, and I…

This wasn't sarcastic at all—any driver of a car is far more dangerous than one in a plane. 9/11 is essentially meaningless in the shadow of auto deaths (to provide a direct comparison). I can't get a firm number on number of plane fatalities in the US (or auto fatalities worldwide), but 9/11 alone would amount to about only 0.04% of total vehicle fatalities in the US since 2000.
if i live to be 90, i'd wish to die quietly in my sleep like my grandpa. not screaming in terror like his passengers.

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…
has anyone made an updated version?
