forecast _for four years prior_.

Whether this is a testiment to efficiency or a harbinger of peak oil, I'm not
entirely certain. Though as an example of the shifts in resource utilisation
following prices, it's instructive.

The efficiency improvements, it should be noted, are in both per _revenue_
passenger mile and per _capacity_ passenger mile. Those result both from an
increased number of seats per aircraft (that's where your legroom's gone),
_and_ in the number of paying butts in those seats, largely courtesy improved
predictive sales / incentives methodologies. And improvements in aircraft
efficiencies. Such as by high-bypass turbofan engines, which require ever
higher, and forward-positioned, mounting systems. Which then affect aircraft
handling and stability....

There are probably limits to both approaches.

My theory is that people hugely overestimate the importance of things they see
and touch.

Flying is _the_ most fossil fuel intensive thing regular people interact with,
so we naturally assume it's the biggest energy user there is.

Heating is actually the biggest user, accounts for 50% of global energy
demand. This includes space heating as well as process heat.

Process heat is useful, only nobody wants to live near industry or nuclear

I lived 6 miles from an operating nuclear power plant for decades. It was
fine. Interestingly, the most pro-nuclear people are often those who live in
the emergency planning zone. It's thought that this is due to the local
