Wood that my dad brought home for work. One the chapter on economics, he had an example calculating the speed at which people of different occupations should drive, based on the differential cost of driving at different speeds and how much per hour they earned.<br /><br />Since 30 years ago, many more people of lesser means fly, their time is worth less, fuel more, and probably there is a realization that when you fly, the whole day is ruined anyways.<br /><br />The 787 started off as a faster machine, but for economic reasons the design was pushed towards higher efficiency. And not much getting around, fuel efficiency tracks the inverse square of air speed, and linear with air density.<br />Anonymousnoreply@blogger.com
