Not quite sure where that came from. In a 737 we figure about 1200# per hour to taxi. And we consider 30 minutes to be a long, boring, inefficient taxi, and an hour would be excruciating for all aboard. Though most exceed 15 minutes. For a sense of scale, I just checked and a 777 burns about 4,000# per hour taxiing. I don’t have easy access to regional jet taxi burns, but I’d bet 600#/hr is about right. @Llama_Llogophile ought to have a decent recollection of those numbers.
FYI … I have no opinion on private jets.
Almost everything associated with the top 0.1% of humanity (or even top 1% of humanity which every $100K/yr US salary slave certainly is) has/have no place in an equal society. But that conclusion pretty well assumes that an economically equal society is in fact some kind of obvious morally or practically desirable goal.
In terms of total fuel consumption, PJs’ collective consumption are a rounding error on the airlines’ collective consumption. And their collective passenger counts, and passenger miles, are likewise a mere rounding error.
Whether we like it or not, it’s what the bulk of humanity does that determines our future course. Not what our fatcats do. See also
