I have not been everywhere, but Ben Gurion in Israel was worse than TSA. There’s some valid reason for that, but it can indeed be more intense than what TSA currently does. I think it’s theatre too, but too many people are comforted by the theatre and believe that the more that there is, the safer that they’ll be.

I wish more people would feel unsafe when flying and stop doing it as often. Might help put a dent in climate change.

  Isn't flying significantly better for the environment than most other forms of travel? Especially over longer distances.

    Last I read, flying takes twice as much energy as driving, which takes twice as much energy as taking a train. Maybe there are other considerations?

      So there's a Wikipedia page about this, but it seems to have conflicting information or I'm reading it wrong... https://en.m.wikipedia.org/wiki/Environmental_impact_of_transport https://en.m.wikipedia.org/wiki/Environmental_impact_of_tran... The table seems to agree with you, however the text below it doesn't (at least not entirely). After trying to decipher how they keep switching units (kg/km per passenger vs kg/mile per passenger), it seems as if the text shows .18 for long flights, .35 for average cars, .08 for long distance busses, and .19 for long distance trains (all units I put here are kg of CO2 emissions per passenger per mile). And that doesn't take into account manufacturing or the impact of roads, but I don't necessarily think that changes the discussion at all. I'm also not sure if those numbers are average capacity or peak capacity (planes are very often mostly full in my experience, while trains are not, and busses even less so, but that's all based on my own memory). So I'm leaving this discussion with more questions than I started with, but my first statement was absolutely wrong!

        > planes are very often mostly full in my experience, while trains are not, and busses even less so. This is going to be very dependent on the route/times. I've flown transatlantic flights where I've had entire rows to myself (on multiple occasions). Trains are regularly running at capacity, especially on commuter lines.
