Smoking on airplanes is the one that just seemed like an accident waiting to happen. And yet there were (relatively) few incidents caused by cigarettes.

IMO purely people management (1:1s, promotions, goal-setting, staffing/resourcing, involvement in hiring).

Interesting. I'd define all of those tasks as the job of a team/tech lead, rather than a manager. I've worked at places where the same person did both roles, and it was not always a great mix.

I wonder if that will remain the case. The input costs for farming are increasing (seed, fertiliser, energy), the output is becoming less predictable (flood, drought) and the grants from DEFRA which are meant to smooth things out have dried up somewhat since Brexit. If farmers are offered a guaranteed income for a field, I suspect they'd take it.

I think that's what Small Modular Reactors (SMR) are hoping to improve? At least the time to build.

Yes, I believe some EVs allow this too.

What if a happy byproduct of pushing for net zero is more investment in renewables, and decoupling the electricity price from gas?

Yep, if you see someone on a scooter with a clipboard attached to the handlebars it's quite likely to be someone studying for The Knowledge.

The UK previously didn't allow small plug in solar panels (the kind that you just plug in to a mains socket) due to, I believe, safety reasons. This has changed within the last few days https://energysavingtrust.org.uk/solar-roadmap/

That seems mad, given the volume of traffic they're working - even without emergencies. My local GA field is single controller, and that's VFR, grass runways, averages 40-50 movements/day.

I don't think this explains understaffing though.

"The lawsuit doesn’t allege incompetent controllers were hired instead of CTI graduates. Instead, it states that the CTI graduates weren’t given the opportunity to demonstrate their competency."

It sounds like they hired different people, rather than fewer.

In the US, airplanes can be cleared for landing while the runway is occupied (you can be number two, three, etc. for landing and still be cleared). It's different in other countries, where you can only be issued a landing clearance if the runway is clear or anticipated to be clear before you land (e.g. the plane before you is already exiting the runway).

ATC recording on https://www.liveatc.net/recordings.php Fire truck was cleared to cross and then told to stop. I'm not sure if they were the only controller working at the time, they continued working after the incident which seems unusual; my understanding is normally they'd be relieved by another controller.

Yep, I've worked at two startups which started to really emphasise The Numbers in weekly all-hands meetings, and how we're all in it together to improve them, etc. Both of those jobs ended in redundancy.

I used a Tesla charger (as a non-Tesla driver) recently. I think their pricing model is pretty good: pay per kWh (varies between peak and off-peak), and if the station is busy they can impose a "congestion charge" for anyone occupying a charger and not charging, or charging above 80% when it's not necessary for their journey (presumably only works for Teslas where the satnav knows about your journey and charge locations).

I guess a train line has a similar risk of security concerns/disruption, vs. trucks which can be re-routed.

Thanks! I'd seen Uber etc. won't cross the bridge, so looks like talking to an actual human is required :)
