>Trip length simply has minimal safety impact. Yes, and trip length is pretty much the only metric that matters as airplanes are faster than everything else. Since planes are so fast, the only thing I "value" when flying is how far I get. >However, while ISS space station also has a great safety record per mile that does not make it safe. For the ISS we don't care about distance though. We care about duration. People aboard the ISS are not travelers.
