I think people read “stronger than steel” and don’t realize that it comes with the caveat “...under a very specific set of circumstances.”

Those wound cylinders are definitely not meant to be loaded in compression like that. No wonder they fail spectacularly .

The video shows an example of a rocket using a yo-yo despin at like 6:58.....

I don’t understand how a driver is expected to intervene if the system screws up...I mean, the Tesla passes that tractor trailer with maybe 3 feet of distance between them. If the system were to malfunction at that exact moment, I would imagine your first and only indication that anything was wrong would be the car…

My grandmother had an old (like 1970s, probably) fridge with a pedal near the bottom that you stepped on and it opened the door for you; no projectors or proximity sensors required.

I work at a $90B/year aerospace company and our $2000 pens at least look at least a little like the Star Wars ships they’re trying to imitate.

There are two aircraft that make me want to cry when I think of them...the SR-71 and the Concorde.

Planes tend to fly below 300 AGL on approach and departure....Kind of want to be on the ground after landing unless you have a real long ladder.

This isn’t much different than the current FAA aircraft registration database. If you search the tail number of any US-registered aircraft you can find the owner’s name and town/city of residence. I’d imagine a database for drones would be nearly identical (since they are, you know, just a type of aircraft). Of course…

Found a local news story on the crash. Driver reports feeling the back end “fall off.” Come to think of it I remember seeing one of the rear axles on the road next to the wreck. I think the whole rig bounced clean off one of the axles....don't think it's supposed to do that....

This happened right in front of where I work! It’s a dump truck, not an 18-wheeler. The chunks of rubble are what poured out of the back during the rollover.
