There’s the whole “disarm doors and crosscheck” announcement by the captain that tells me that they are deactivated after landing.

More likely in this case the left hand didn’t know what the right hand was doing. The MCAS was modified due to mission creep and in the process went to where a single point of failure would cause the system to fail in the worst possible way. It doesn’t help that, to save agency costs, some of the certification checks…

Hybrids could certainly help with the battery supply issue.

I guess I’ll be the one to chime in with the obligatory thorium reactors pitch. Oak Ridge National Laboratory ran molten salt thorium reactor experiments from the 60s until 1976. The US dropped thorium in favor of PWRs, which could be used in submarines. Thanks Admiral Rickover.

Which means that improvements in urban areas would give us the most bang for the buck. US cities hold over 60% of the US population.

Drag force depends upon the square of the velocity, and there’s only so much you can do the decrease drag. Turbofans can’t go too fast supersonic before they lose so much efficiency that a pure jet is better.

There’s a problem with it having a “much broader mission” than the F-22. They’re trying to shoehorn one airframe into doing three different roles. A lot of compromises were made, all in the name of “it’ll cost less if we use one basic design for all three services.” It was a bad call, Ripley. It was a bad call.

Another “Jack of all trades, master of none” aircraft.

You just know that the Air Force will come up with reasons that they can’t do ground support with their expensive, shiny new toy. That’s a major reason I’d like to see the A-10 keep going, albeit with upgrades to protect against MANPADS.

If the plane was gliding it’s not going to be moving as fast as it can powered at altitude. Also, max speed at altitude is higher than max speed at low altitudes (the air is denser). I’m sure that an unpowered airliner in a dive could get going pretty fast. But the faster you want to go forward, the faster you have to…

R12 replacement. Not a great idea. If a repair tech has to evacuate the system and doesn’t know that it’s propane, things could end up poorly. I’m assuming It was on fire when I got here does his own work though.

Parked ICE vehicle fires: Kias. F150 cruse control recall.

Headsets I think that even in states where they are allowed, if you couldn’t hear something like a siren because you were playing music too loud, you could be ticketed. Also, I’m surprised the Cali police don’t crack down on that since it’s illegal there.

And yet it’s the cars fault. I love stupid laws...

“ICE car fires to my knowledge generally don’t start when you’re parked”

That’s right, the batteries are only good for about 30 days after they activate. The cold at the bottom of the ocean doesn’t help with the chemical reactions that makes batteries work either.

Black boxes are designed to survive impact at hundreds of miles per hour into the ground. While hitting water at those speeds isn’t much different, they most likely did survive. How long they’d stay readable after years in the ocean is, of course, not easily determined.

Ads use to pay for newspapers (okay, ads were the lions share of newspapers revenue). We can argue about how things are different now, but now we’re supposed to pay for a subscription AND have obnoxious ads shoved down our throats? We are paying.

That’s fine for regular readers, but what about those of us who only care about seeing a few articles each month? With newsprint back in the day, you could not have a subscription but still purchase one day’s paper for far less than a dollar. Or you could go to the library and not pay anything as often as you want.

I just don’t get it. Were the people making decisions for the types of ads used on these sites picked on in school? Do any of them think that using the most annoying forms of ads possible makes people want to click on them more?
