That's a really big if , especially since not all traffic has a transponder, and not all airports are towered. It would need to understand how to visually look for traffic with a camera, and understand what intentions other pilots are

I wasn't there and don't know all the facts, so I'm not going to attempt to assign blame in this specific instance. But speaking generally, I'll just say: If you're flying in VMC conditions (good weather), you'

I think it's good to read papers and be curious. It's also good to work with your doctors (as you seem to have done), have a discussion, and mutually agree on a plan of treatment. Experts don't know everything. But they proba

Some folks actually were taught to use em-dashes as part of their normal writing, especially if you've taken a technical writing course. I dislike that people think you're an AI if you're using proper typography. :(

Passports are inherently decentralized, which is needed because not all countries cooperate with each other - or have the same budget for technology/security. It's really way something at global scale could work. (There are nation

Yes, that's correct. There have been apps on iOS and Android that can read your passport via NFC for ages. As you noted, all you need is the plaintext information printed on the photo page to generate the Basic Access Control key, whic

Airplane autopilots are basically just cruise control. You still have a human in the loop double checking everything constantly and stepping in as soon as something isn’t routine (which is actually quite frequently).

Air traffic also requires the use of visual skills - and it’s harder than driving because of the small target size and wide field of view. “See and avoid” has a very high priority in the cockpit - not everything out there is on radar, not e

Yes, you're right. Thanks! (I just edited my post, and also linked to a 2019 law that guarantees back-pay for both essential and non-essential federal workers.)

There's definitely nuance here. Pure oxygen puts oxidative stress on your cells. Your body can handle that just fine at 1 atm, but at elevated partial pressures the increased concentration will (quickly) overwhelm your cellular mechani

You actually don't need insurance to fly a plane (in the US). That said, I don't know of any aircraft operator who doesn't have some form of insurance. If nothing else because the banks demand it.
