@MrMenApocalypse @CampaignNhs @charlie444b @NHSuk I developed AF after decades of following NHS advice to ignore my symptoms and get more exercise. This is what happened after I was diagnosed:

There are a lot of people who get a very good service from the NHS, but they have no conception that there are others who don't.

The physics of what's happening in that 0.1 seconds of contact should bother you.
Those tires are completely stationary when they hit the ground. The plane is moving at 250 km/h. For the first fraction of a second, the rubber isn't rolling. It's skidding. Pure friction has to accelerate 22 wheels, each weighing 120 kg, from zero to 155 mph in roughly a tenth of a second.
The tread surface goes from -50°C at cruising altitude to over 200°C at the moment of contact. A 250-degree temperature swing in 0.1 seconds. The smoke you see at every commercial landing is rubber vaporizing off the tire surface. Studies at Manchester and Heathrow found that tire smoke at touchdown produces a greater magnitude of particulate emissions than the jet engines themselves.
The tires are inflated to 200 PSI, six times your car's tire pressure, and they're filled with nitrogen instead of air. Regular air contains moisture that would flash to steam and oxygen that could combust at those friction temperatures. Nitrogen eliminates both risks.
Each tire costs $5,500 and lasts about 250 landings before replacement. The A380 carries 22 of them. At max landing weight, those 22 contact patches are distributing 391 metric tons across roughly 15 square feet of rubber. That's 57,000 pounds per square foot.
The reason they don't pre-spin the wheels before landing, which would eliminate the skid and save millions in tire wear, is weight. Adding electric motors to 22 wheels increases fuel burn on every single flight. The math says it's cheaper to vaporize rubber 250 times and buy new tires than to carry the motors.

This is the most satisfying video I've ever seen. Slow-motion footage of an A380's weight on wheels during touchdown.

@but_cyclists I don't see the point, it must be an utter PITA to ride in traffic.

@nthng2c576169 @OrevaZSN As he said, we're not killing the planet.
Earth survived for billions of years before we arrived, and if we make it unsurvivable for humans, it will be just fine once we're all gone.

Honestly, I’m sick and tired of grown adults calling the climate crisis a hoax. It’s not even a debate, the science has been settled for decades. Your ignorance is not just embarrassing, it is actively destroying the planet and every living thing on it.

@AetherFox_ " We suggest that current consumer orientated/learning approaches that advise staff to ‘take complaints seriously’ or ‘receive them as gifts’ are unlikely, in themselves, to convince care professionals of the value of patient insight and experiential knowledge"
English
@AetherFox_ "patients’ motives for complaining were generally discussed in terms of mistake, irrationality or illegitimacy"
English
Medicine consistently and flagrantly flips the script to blame the patient for its own failures.
- Being socially isolated due to pain becomes you are in pain due to being socially isolated.
- Deconditioning due to disability becomes you are disabled because you are deconditioned.
- Depression or distress due to disease burden becomes you have disease burden because you are depressed or distressed.
- Nerve damage due to untreated pain becomes you have pain because your nerves are too sensitive.
And so on and so forth.

@DeanSmi47962704 When I was commuting by car, I spent a total of 3500 hours being held up by other cars, and in all that time, the number of occasions I was held up by bikes were so rare I don't recall any.

@MaCgroupUK @Daveholt1070707 Cycling is a hobby for some and transport for others, just like motoring.
English
@Daveholt1070707 The tax payers money that's wasted on cycling !
It's your hobby, you pay extra for it !
English
Have the cyclists that have been in hibernation, until the sun came out, now missed their chance, as now health experts are warning against going out in the sun & riding a bike etc .
So once again expensive cycling is a waste
Much better in an air conditioned vehicle !
English
I bought an aircon and it’s great.
You should buy an aircon for your home too if you feel uncomfortable in the heat.
This should not be controversial.
Looking for Growth@lfg_uk
Britain will do literally anything but install air conditioning in new homes.

@anon_opin A fair bit of the blame for that can be placed with the consumer: obsessing about ever smaller gadgets without any thought for what it takes to achieve it.

If you ever needed proof that capitalism is happy to destroy the world for a few quid, it's in the fact that you can't pop the back off your phone to replace the battery any more.

@RichardWellings The charges that motorists pay don't cover the costs. And they don't even keep pace with general inflation either, let alone the inflation of public transport.
English
Motorists pay massive taxes to use the roads, but they're increasingly being banned from significant parts of the network. The policy is now spreading to rural areas, where cars are essential, as part of the power elite's plan to restrict travel. itv.com/news/meridian/…

@stealyoredbull I remember when computers were as big as a room, and didn't have the internet.
English
Life was better when there was a ‘computer room.’ Where you had to physically enter the room to get on the internet and then log off and leave that room and the internet stayed behind. The minute we were able to take it with us in our pockets that’s when society collapsed fully

@Turbinetraveler This demonstrates a breath taking lack of feel for mechanics from people you'd expect to know better.

The NTSB later found that the N110AA DC-10 disaster began weeks before the AA191 crash during a maintenance procedure at American Airlines’ Tulsa facility.
McDonnell Douglas recommended removing the engine and pylon separately, but American, Continental, and United used a faster shortcut by removing them together to save time and labor hours.
During maintenance on Flight 191’s aircraft, a slight forklift misalignment jammed the pylon against the wing, creating a small structural crack that went unnoticed.
Over the next 8 weeks, the crack grew with every flight cycle until the pylon finally failed during takeoff rotation, causing the entire engine to tear away from the wing.
Fleet inspections afterward found similar damage on other DC-10s as well.

AMERICAN AIRLINES FLIGHT 191 — THE DAY THE DC-10 CHANGED AVIATION FOREVER 49 years ago today, May 25, 1979, American Airlines Flight 191 crashed moments after takeoff from Chicago O’Hare, killing all 271 people on board and 2 on the ground. It remains the deadliest single-aircraft crash in U.S. history. The McDonnell Douglas DC-10 had just rotated off Runway 32R when the unthinkable happened: the entire No.1 left engine and pylon tore away from the wing, flipped over the aircraft, and slammed onto the runway. The separation severed critical hydraulic and electrical systems, causing the left wing’s leading-edge slats to retract unexpectedly. With the right wing still producing full lift and thrust, the aircraft became catastrophically unbalanced. The left wing stalled first. Within seconds, the DC-10 rolled violently to a 112° bank angle, nearly inverted, before crashing into a field near a trailer park at the end of the runway. Investigators later discovered the root cause was improper maintenance procedures. To save time, the engine and pylon had been removed together using a forklift instead of following McDonnell Douglas’ approved method. The process damaged the pylon structure, creating cracks that went unnoticed until catastrophic failure occurred during takeoff. Even more tragic: simulator tests later proved the crew did almost everything correctly. Critical stall warning systems had been disabled by the electrical failure, leaving the pilots with no indication the left wing was stalling. Flight 191 reshaped aviation safety forever, leading to stricter maintenance oversight, redesigned inspection procedures, and independent stall warning systems for both pilots. A tragedy that changed aviation history forever. Video shows recreation footage.

@JamesMelville Recover from what? If people can't stay indoors for a few weeks without falling to bits they need to get a grip.

Britain has not fully recovered from the Covid lockdowns era. You can feel the decline and loss of energy everywhere.

@DaveMForrester @paullewismoney Open the windows at night to let the warm air out, and the moths in.
English
@paullewismoney Temperature management helps more. If it's warmer outside than it is inside keep all the windows closed to keep the cool air in. Then at the end of the day when it's cooler outside than it is inside, open all the windows and let the warm air out. It's basic thermodynamics.

I wonder how many people will order a portable air-conditioner today not realising it needs a fat tube out of a window to vent the hot air and that by the time it arrives it will be 23C?

@DougalMcShoogle @MbarkCherguia The entitled ones are the motorists who park wherever they see fit.

@MbarkCherguia The farmer is an entitled cunt that needs locking up for ten years imo.

A guy who tried to stop a farmer from flipping his mate’s hire car with a forklift says he’s “lucky to be alive.” 🚜💥
The drivers blocked the farm gate, refused to move, and allegedly punched the farmer first.
Was the farmer completely justified or did he go way too far? 👇
