Airline ‘adjacent’, but DEFINITELY worth reading, and knowing about. (The other links in the article are fascinating, Hertz is a serious bunch of shit-weasels).
Oh yeah, one time I rented from them and they thought the previous person still had it. They couldn't "fix" this in their system, so it ended up being totally free...and I could have sold the car on the black market.

so this tells me that there is no fire break between the engine pylon (like expanding fire resistant foam is required for openings in building construction) and the passenger cabin. glad I don't fly anywhere

There absolutely is, but pressurization systems use bleed air from the engines which also runs through the environmental air conditioning packs as well. This can be shut off and one engine is sufficient, but if left on, anything burning in-cowl could theoretically go into this line and into the cabin. This isn't fire, this is smoke and fumes.

I love the little whiff of Jet-A you get after engine start and the AC is turned back on.

That's pretty normal time to descend that far. At first 35,000 or whatever the initial decent rate is around 4000fpm, it gets less as the wind gets thicker as you get lower.

The old 3:1 rule is to plan out a 280kt descent, which is what most airliners shoot for, for every 1000 feet of difference between cruise and your altitude restriction/approach altitude, you need 3 miles to descend. So 27 thousand feet would mean starting 81 miles back, and at 280kts, it would take about 13 min or so.

You want to descend quickly when pressure is lost, because of breathing or some horseshit.

Actually, no, you don't. Most airlines teach put the autopilot on, wheel down the altitude in the setting-window, set the autopilot and go. Pilots were doing way too many crazy things during emergency descents with poor aircraft control, or even losing control. Much better to let the computer descend it, safely. As I said before, you are descending into thicker air pretty damn fast at first. Admittedly, I did learn this while flying a 737.
