Things are rough out there for sure.
Part of the Part 23 (certified aircraft rules) process is demonstrating spin recovery. The Lancair is experimental so it's not Part 23. Cirrus said, "We put in a parachute instead of demonstrating spin recovery." To which the FAA said, "OK, that works for us."
Since the Cirrus prohibits spins (most certified aircraft do) and Cirrus never demonstrated it officially, I only have the word of random comments on the internet to go with. The assumed state is, "The SR22 has poor recovery characteristics from spins and the manufacturer states in the POH that CAPS is the only recovery method." Maybe it's not all that bad, but at pattern altitude (this has sadly been demonstrated) I'm sure it's fatal.
Airlines (which I don't have personal experience with) do it with a two person cross check.

> It would take 700 trips by bicycle to equal the damage caused by one Smart Car. It would take 17,059 trips by bike to equal the damage caused by an average car. And it would take 364,520 bike trips to equal the damage caused by just one Hummer H2. https://streets.mn/2016/07/07/chart-of-the-day-vehicle-weigh...
When this all comes together, every cycling trip I take is a car left parked and that benefits everybody. That's why we don't tax cyclists for infrastructure and why it's counter-productive to raise it as an issue.
Possibly something like this one: https://www.youtube.com/watch?v=ZVQTt4CgNZs
Human, if you're wondering still.
The bicycle leaves me exposed in traffic and more often than not wearing a t-shirt for heat control.
Just to give a different perspective on it.

I think pilots get a lot of situational awareness as well from listening to the common frequency.
For an ISP, they do this by peering locally with major providers. Google, Twitter, Facebook, Netflix, etc. all have very large networks and will openly connect at Meet Me points in open and private internet exchange sites as will CDN providers. https://en.wikipedia.org/wiki/Internet_exchange_point. Some providers such as Google and Netflix will even install local caching servers that you can reach from your network if you have enough traffic. As a small ISP, you try to take advantage of all of that.
Your option of last resort is the Tier 1 upstream provider. That's for anything where you can't get to it via local transit peering. This should be a smaller percentage of your traffic and it costs more than peering arrangements. The nature of a DDOS is going to fill that smallest and most expensive connection that provides the filler access to the majority of the world but doesn't handle the majority of the traffic.
Even as a hosting provider, it doesn't have to be overselling. If you have 250 1Gbps customers and 250 Gbps of bandwidth, you'll still be useless in the face of 250 Gbps of junk traffic. Pick a random packet and tell me what should decide if it is dropped is something that has to be determined upstream of the saturated link.
EDPnet looks pretty well-connected too: https://bgp.he.net/AS9031#_ix
What's being talked about here is thermal energy storage. Ice is created overnight (ok, like a refrigerator), but then during the daytime used to supplement or replace the refrigeration cycle of the compressor to reduce electric load while still providing cooling. I can't quickly find an article (edit: found a 2016 paper, see comments about Boothbay on page page 3-4: https://www.aceee.org/files/proceedings/2016/data/papers/3_2...), but it's memorable to me that an island in Maine installed these systems instead of spending more on replacing the distribution line to the island the handle the peak daytime cooling load.
My last gaming computer took me 9 years along with only an SSD addition, RAM upgrade, and video card change halfway through. It was only Microsoft Flight Simulator that made me jump up and damn... my timing was a just a little too early on the beefy video card.
American policing has inherited this idea.
Cattle is a threshold, but when the same problem keeps coming up it's time to call the vet. http://rachelbythebay.com/w/ has many good examples of this, some submitted and voted up here.
