Treason doth never prosper, what’s the reason? For if it prosper, none dare call it Treason.

My $0.02:

- The stick-and-rudder skills aren’t hard and not the main reason people die. It’s the decision making that kills.

- The “faster to fly” than drive for me starts at about 3 hrs drive (wind, preflight time, takeoff / climb / landing time, deviations by ATC, etc). My indicated airspeed is roughly your true btw.

- Looks and feels like Cirrus with AI. I am missing barn doors for luggage and dogs; 200 kts cruise; 6 hrs with tip tanks; and gross to actually do it. I’ll stick with my Bonanza.

- Main problem you will face is insurance. It will be expensive if even obtainable for low experienced pilots.

With 10+% annual inflation in US in the last 2-3 years, 20+ P/E doesn’t look bad at all. Actually anything under 40 or so should be a strong buy.

Thanks for explanation. I will read the code to see how sharing works.

That’s not what I saw in the code but I didn’t spend much time so I might be wrong. I’ll check it more carefully later. But if this indeed is whole DB then it’s very limited use case.

Does the server reads specific rows from spam numbers DB or the whole database?

Evil server stores BOTH encrypted and plain text phone number in the same db row

Exactly, plain text phone number in the same db row

If we assume that server is “evil” then the server can store both PIR encrypted and plain text phone number in the same row in the database and when this row is read, simply log plain text phone number. What do I miss here? We can send PIR request and trust server not to do the above; or we can send plain text phone number and trust server not to log it — what’s the difference?

Since for telescope what matters is the surface size of the mirror (light collected is proportional to surface which is proportional to r^2), the 9m telescope is ~1.9x better than 6.5m one. This is a big difference. Not even counting the loses from a non perfect alignment of a folding mirror compared to a fixed one.

Not sure what exactly are you looking for. Bunch of info is on FAA website, for example:

DME (distance measuring equipment) is much simpler than LORAN. However, navigation computers can use multiple VOR / DME signals to compute position similar to LORAN or GPS. The problem is that DME / VOR are typically limited to 50-200nm (and even lower at lower altitudes) which requires extensive network to make it comparable to GPS / LORAN.

Botched go around killed many pilots. May be trimmed too much up for landing with flaps and didn’t push nose down hard enough. In general, touch and goes in a high performance planes is not a good idea (no time for checklists, runway length, and actually wrong muscle memory for real takeoffs / landings). RIP.

I also got my license around that time with eb6, paper charts, VORs, NDB approaches, … and I don’t miss it a bit. Nostalgia - yes. But not missing it. I like to fly direct, I like to get LPV approach to 200 feet at an airport that would never ever ever would had had an ILS installed, I like traffic and weather on ADSB, I like my ForeFlight, and list goes on. The new technology helps to make flying safer. Yes, you need to know how to use all of this. And yes, it’s complicated. But the benefits are great too.
