Even in the US, I don't know many friends with enough living space to have an entire spare guest room. When friends visit, they sleep on the living room couch or an air mattress. Is this not typical?

Does anybody else find these AI-authored blog posts difficult to read? Something about the writing style and structure just feels unnatural, it's hard put my finger on it. At the very least, the writing takes way too long to get to a p

That could still get prohibitively expensive. Take the example from this article, where there's only one person still using the paper ticket option... I could see someone arguing you need a specially trained staff member or supervisor

It depends on whether the ticket is considered a criminal or civil matter in the US. For a criminal case, yes, they need to prove "beyond a reasonable doubt" - which would require that you are positively identified as the driver.

FileMarker Pro had a dedicated server product (FileMaker Server) that you could use for multi-user access. Claris still sells it: https://www.claris.com/filemaker/ Microsoft Access was strictly file based. You could dr

Yes, though that's separate from the flight plan. There's also several different ways to transmit the passenger manifest to CBP - including over a CBP-provided VPN and IATA "Type B" messages sent through ARINC/SITA.

Nit: If you're filing a flight plan, you do it with the country you're departing from. Even if you're piloting an aircraft departing into the US, it wouldn't have any effect on operations if you couldn't reach US we

The NOTAM system certainly does allow users to specify the end date for a TFR as "PERM" (Permanent). For example, see the Disneyland TFR (FDC 4/3635): https://tfr.faa.gov/tfr3/?page=detail_4_3635

The part about power outages is certainly true in Tahoe. I grew up there and remember a week-long power outage as a kid, since the snow took out the feeder lines from both CA and NV simultaneously. Outages that long aren't common, but

Based on the published dimensions, it's almost the exact same size as a Toyota 4Runner - which I'd consider a midsize SUV. Comparison image: https://www.reddit.com/r/RivianR2/comments/1inep90/r2

Cars don't need high octane fuel, aircraft do. Outside of the absolute smallest aircraft, you can't get enough power out of automobile gasoline. They started looking at it 14 years ago, but there's been tons of bureaucratic r

One hour really isn't enough time. You can spend 30-40 minutes just getting in/out of busy terminal airspace, which would only leave 20-30 minutes for instruction - which is nothing. Most flight lessons are closer to 1.5 hours for

No, piston aircraft cannot run on Jet-A. That would cause detonation and the engine would quite literally self-destruct within minutes - likely during takeoff when the engine is at highest power. There's been some trials of battery-pow

At least in the US, the current proposed plan is to phase out leaded avgas by 2030: https://www.faa.gov/aircraft/draft_docs/draft_unleaded_avgas...

Piston aircraft are vital to training new pilots. Without the piston fleet, you wouldn't have anybody flying anything larger. Not to mention they're frequently used for air ambulance flights, survey work, and law enforcement. The

There definitely is urgency to phase out leaded aviation gasoline. The FAA is proposing that we phase it out by 2030 - just 4 years from now - even though we still haven't agreed on which of the 3 competing gas blends to standardize on

Sure, but the people doing the recycling have no idea what's inside of it.

The problem is you can’t find any company willing to recycle them. Because of the nicotine content, I’ve heard e-waste recyclers consider them hazardous waste and refuse to touch them.

The biggest tangible benefit is you don't need to worry about NAT port mapping any more. Every device can have a public address, and you can have multiple servers exposing services on the same port without a conflict. (The flip side is

NAT doesn't solve everything, and creates a whole new class of problems that you can just avoid by adopting IPv6 natively. And it's definitely not being ignored at larger companies. In particular, just off the top of my head... -

They do not used bottled (or boxed) water for coffee. That comes from the coffee machine built into the galley, which uses the aircraft’s onboard potable water tanks. Those tanks are filled from a hose by the ground crew during refueling. (

Yes, and more... You can use different antenna designs for a more directional radar beam. Or tilt the beam upwards to steer it around obstacles. You can also build a moving-target detector by looking at doppler shift to filter out objects t
