airplanes

New airplanes can easily run $200k+, so people hold on to airplanes for decades.

These non-random intents of pilots mean that airplanes get a lot closer together than you would otherwise think.

I think the reason is that the places airplanes go is not random.

To start an airline you need large investments (you need to rent or purchase airplanes, crew, fuel).

They fly so fast that she has far less time to react and to redirect other airplanes.

If airplanes felt as often as surgery fails, people would not travel on them all the time.

Certainly not to the degree that commercial airplanes are vetted, and even those systems aren't invulnerable.

It's easy to state the obvious that Uber for airlines would not be like Uber, because most people don't own private airplanes.

ADS-B [0] is going to be required equipment in all airplanes by 2020.

Waterfall (the stupid kind, not the way it was meant to be done, which is quite good for projects involving airplanes and such).

Electric airplanes already exist, and will continue to improve for decades to come.

And that only broadcasts your position; a separate ADS-B receiver must also be purchased if you want to actually see other airplanes around you.

Lawrence Lessig goes into it a bit in Free Culture but the basic gist is that when you owned land and a house, you owned the land "up to God." Then airplanes came around and suddenly you didn't actually own all the area above your house, just a portion (relatively) near it.

> "Yet if you could open the airlocks and stare down its length with a telescope, you would see airplanes on final approach to Newark Airport, three thousand miles away!" Newark Airport is in a solid southwest heading from Weehawken.

Airplanes are horribly expensive and have a very long service life.

Airplanes are pretty simple compared to most modern cars.
