I understand this is asked every time, but honestly in the 2 months of Covid19 and 20 years of post-9/11, I still haven't seen an answer that makes sense:<p>Why are we obsessing over airplane security so much, but completely ignoring ground transportation?<p>Never mind Metro/Subway/Underground, which we can claim not every city has (I'd still imagine total number of subway passengers daily outweighs airplane passengers or is at least comparable) - what about buses? Trains? Street cars and trams?<p>Any airplane I've ever flown had better filtering and circulation, more spacing and better hygiene, than any bus I've ever ridden in. Every airport terminal was more spacious than every indoors bus or train terminal. Across countries and continents this ratio has held true.<p>So why this <i>obsession</i> with airplanes as the vulnerable part of the equation? Is it all just... human inability to calculate risks and our focus on the "flashy"?<p>I've done 50-75 flights a year over last 10 years; none last 2 months obviously, and I don't foresee any soon; but I'm DEFINITELY not going to take our friendly neighbourhood Toronto subway if I can help it, as much as it's the key to fighting traffic and pollution.<p>This should be throwing our entire transportation industry into disarray and restart fundamental discussions about urban planning and urban landscaping of the future... and yet I only ever see the airline industry mentioned.
