I think the astronauts health makes them much less likely to die from Corona than 0.3% but exposing the current crew of the IIS does not sound like a good idea either.

Fatality rate is one thing, but being in a small space can cause high concentrations of virus and any health complication in space is a big deal.

A catastrophic failure is definitely a risk, but not sure how its magnitude should diminish our caution when it comes to bringing the virus to the space station (by your calc, it lowers the risk only by 5%).

And still Ken Mattingly was pulled from Apollo 13 3 days before takeoff because of a potential exposure to measles. In the live video, most of the technicians and even Musk are wearing masks, most of them staying at some distance though. I doubt they were all quarantined for the last 2 weeks.

3x levered nasdaq 100 would give you an annual volatility of at least 30-50%, occasionally much much higher. The crazy thing is that medallion presumably achieved this with a very small volatility and no significant drawdowns. Nasdaq 100 was down -42% in 2008, so levered 3x you would be out of business.

This is great. An idea: make the aircraft names link to corresponding wikipedia pages or other sources of info on the specific planes.
