It’s right there, friend.

25,000lb. Reading the article it says “more than 25,000 lb”.

We should assume they used a highly efficient airfoil that can maintain the most efficient possible cruise for the demonstration aircraft probably at L/D max if they’e looking for time aloft, so I doubt it’s even worth considering top speed or ceiling. It would be interesting to know what NACA profile they used and what the top speed characteristics would be.

Edit: looks like a Vne of 140 Kias. This is not a fast aircraft. Also a minimal useful load. If you make a couple clicks through to the site of the test it’ll give you more info.

I did my best to find any technical data about the flight. Couldn’t find any actual numbers. FWIW it’s not intended to be a standalone method of powering the aircraft for commercial use; they plan on making it a hybrid, which makes far more sense as far as range and payload are concerned. Best guess a 25000 lb aircraft like this will probably cruise around 120-150Kt at a nice, slow, efficient airspeed for a test like this. So maybe a 40-50 mile flight because “air time” probably started as soon as they lifted off.

A lot of our critical infrastructure is connected. From power generation to water to sewer. All have been subject to hacking attempts, some successful.

I have also been saying for quite a long time that these things should not be connected in a way that they can be damaged or disabled by internet.

But y’know, put it all on the web and write controller software for centralized remote operation and monitoring so you can fire people and run the system with less people for more profit.

TL;DR: it’s not the screens or tech’s fault. It’s the overall pressure to lower standards and people that for whatever reason can’t work with tech.

After seeing my kids go through school I’d say the chief issues with performance are external. Tech and screens are like any tool, they’re only as good as the user.

Parents and society place less importance on education and critical thinking, in fact they often insult it. Parents teach their kids that they’re not responsible for their failings, it’s the teacher’s or the school’s fault. Parent’s don’t have the knowledge to help with the tech, nor will they police the kid’s use of the tech, either because they dgaf or can’t understand it. Teaching standards keep moving the goalposts to help the least common denominator. Teachers also aren’t allowed to teach in a way, there’s always some “do-gooder” latest study that’s supposed to teach kids better, but it’s bullshit management worried more about studies and metrics than just teaching. Teachers spend more time jumping through hoops than teaching.
