@TomBlackmore90 Friend of mine had 3 R26R's, he loved his Meganes. Sadly passed away in 2023.

Perhaps in more exciting news… 1 of just 4 remaining French Racing Blue R26.R’s in the UK. Just 11,500 miles, 3 owners, Cage, Titanium Exhaust, Climate, folding mirrors, decal delete (from factory) & absolutely minty mint! A very special car I’ve tried to buy for years 🦄

@OCDaboutCars I could do better than that chump, and I would be a terrible choice!

Allow me to put forward *rummages in cupboard* This potato.

@OCDaboutCars Monograde - designed for specific operating conditions with a relatively constant temperature.... i guess 75w90 would be fine if you can establish what that operating temperature is!

Gear oils, talk to me. I thought most oils had a cold/hot weight? but it turns out the Yaris specifies 75w 🤷‍♂️ Extra curious as I've got ~2l of 75/90 leftover from the MX5 which could save me £20 😄

@OCDaboutCars @TomTalksCars They are as bad as the last lot but are any of the other options any better? I dont want Farage in No10 for sure.

@TomTalksCars They got in off the back of false promises and because people were at a point of "Fuck it. We have to try something different!" And they've completely spaffed it up a wall. If (when 🤞) they go, I can't see Labour getting in again in my lifetime.

Always a tweet.

Scientists knew this moon existed before they ever saw it. They spotted these waves in Saturn's rings in 2005 and realized something had to be making them. They did the math and found it. The moon is about the size of Mount Everest. It's called Daphnis. About 5 miles across, shaped like a frozen potato, orbiting inside a 26-mile-wide gap in Saturn's brightest ring. As it moves through, its gravity yanks on the ice along the edges of that gap, pulling chunks up and letting them fall back down. Those are the waves in the photo. They rise almost a mile above the rest of the ring. Saturn's rings are huge. Stretched end to end, they'd go three-quarters of the way from Earth to the Moon. They're also absurdly thin. In places, they're about 30 feet top to bottom. The height of a three-story house. If you shrunk the whole ring down to the size of a football field, it would be thinner than a piece of paper. So a mountain-sized moon is pushing mile-high walls of ice out of a sheet thinner than paper. This is also how planets get built. When a new star is born, it's surrounded by a thin, spinning pancake of dust and ice. If a chunk of rock in that pancake grows big enough, its gravity starts sweeping material out of its path, carving a gap. Do that for a few hundred million years and you've got a planet. What the Cassini spacecraft photographed at Saturn is that exact process, happening in miniature, right now. Telescopes on Earth have spotted the same ring-and-gap patterns around other young stars, where baby planets are carving gaps just like Daphnis is here. Saturn's rings are also young. Maybe 100 to 200 million years old, which means they formed during the age of dinosaurs. And Cassini's data showed they're disappearing. Ice is raining down onto Saturn fast enough to empty them out in another 100 million years. We happen to be alive during one of the only windows in Saturn's history when any of this exists.

Went to Autodrome de Linas Montlhery to see the holy grail line up of Renault 21 Turbo's. Did not disappoint. Ice land speed record car 88 superproduction 89 superproduction Gouhier Europa Cup 🥳

@OCDaboutCars A likely story 😂

FFS 🤦‍♂️ My screen just froze for a second, and while frantically stabbing at it, guess what I clicked on. There go my algorithms 😐 Why the f**k was that suggested in the first place?!

The voice over is absolutely epic 😂

@OCDaboutCars 1) Don't have 100k 😂

@DaveL485 Neither could I, for 2x main reasons 😄

We're not in crazy COVID car market times anymore Toto. This car would have been ~£175k a couple of years ago. Legit mint too by the looks of things. Someone got a decent deal on this at £103k (~£110k with fees) at auction yesterday.

@anishmoonka What is done on a booster "Refurb"? How much of the 30+ landing rocket is original? Are all the engines the same ones for example?

The rocket in this video has already carried NASA astronauts to space. Yesterday it flew again. Seventh time. Refurbishing it between flights costs about $250,000, according to Musk, while building a new one from scratch runs $74 million. That bottom section of the rocket, the tall part you see landing in the clip, is the expensive piece. Nine engines, fuel tanks, landing legs, onboard computers, all of it used to be thrown away after every single launch. Like buying a brand-new 737 and scrapping it after one flight. SpaceX figured out how to land it and fly it again, and they've now done that 596 times out of 609 attempts. The current version of the rocket lands successfully 99% of the time. One single rocket has flown 34 separate missions. Guinness World Record. SpaceX has cleared each one for up to 40 flights. Launching a kilogram of cargo to space (about 2.2 pounds, roughly a bag of flour) on the old Space Shuttle cost $54,500. On a reused Falcon 9, that same kilogram costs $2,720. A 20x drop. Most of the $15 million SpaceX spends per reused launch goes to the top half of the rocket, which they still throw away every time. SpaceX launched 134 rockets in 2024. That broke every annual record in spaceflight history, including ones set by the Soviet Union during the Cold War. In 2026, they've already flown 44 missions by April 11, averaging one launch every 2.2 days. About 20 rockets rotate through the active fleet, and the fastest a single rocket has turned around between flights is 9 days. This specific flight delivered 11,000 pounds of food, experiments, and supplies to astronauts on the Space Station. Northrop Grumman, a major defense contractor, hired SpaceX for the job because their own rocket got retired in 2023 after the Ukraine war cut off the Russian and Ukrainian parts it depended on. Their replacement rocket, being built with a smaller company called Firefly, still isn't ready. They had to buy this extra SpaceX flight last September. "Falcon has landed" is three words. Behind them: 596 landings, a cost per flight that would have been science fiction 15 years ago, and a launch pace no country or company on Earth comes close to matching.

@MCCCANM Fascinating!

The “wavy” lines in the canopy glass (plastic) are not antennas…they are explosive cords. In the movies, an ejection is preceded by the jet’s canopy being blown off. “Goose” got killed in Top Gun because it didn’t happen fast enough & the seat hit the canopy. Some jets took a different approach, though. Rather than jettison the canopy, which is complicated & can fail, why not just blow it up? Shatter it into a thousand pieces that won’t hurt the pilot. This can shorten the ejection sequence, too, as you don’t need to allow as much time for the canopy to clear the ejection path (we’re talking fractions of a second, but still…). Anyway, this is the design they came up with. It’s known as a “Canopy Fracturing System”. It’s automatically triggered when you pull the ejection handle, but can be manually triggered as well without ejecting. I suppose that might be useful if smoke is accumulating in the cockpit. Now, jets that blow the whole canopy off instead of blowing it up have a somewhat complicated system to accomplish this. The system has to release the hooks locking the canopy onto the jet; it often does this by pushing hot gas from an explosive through tubes that push the hooks back (there are several methods, though). Kind of like firing a gun. Both systems can fail, though the explosive cord is considered very reliable…they put it in the F-35 (and I had it on the T-6). As a backup, the top of the ejection seat has a little pointy end on it. In theory, this point should hit the canopy before your head does if the canopy is still there in an ejection, shattering it before the canopy shatters your spine. I’d guess that has happened before, but I can’t recall any examples. Older jets sometimes got around all of this by just ejecting you downward. A hole would open up in the floor & the seat departs that way. The disadvantage here is obvious…you’ll have a higher minimum safe ejection altitude. This system still exists in the B-52. The seats back then were not quite as sophisticated as they are now… Today’s seats detect your orientation. If you eject while inverted, the seat will fire just enough to get you out of the jet, then right itself to point upward & fire again. When the seat has done its job, it automatically cuts the belts & straps that held you in & departs. The seat itself contains the parachute…so when you strap in, you’re strapping on the parachute…obviously, the seat doesn’t cut that, it’s the parting gift. The parachute has a barometric sensor that automatically deploys it if below a set altitude. If flying over high terrain (higher than the standard set altitude), you can rig it to immediately deploy the parachute on seat separation. The parachute also has an emergency oxygen bottle. This is not automatic, but pulling a cord will start the short flow of oxygen (I think it’s like 4 or 5 minutes, can’t remember). The hose for your oxygen mask is connected to the jet but is designed to break-away from the jet at the connection in an ejection; a smaller hose connects to a point on the parachute harness that will provide the emergency oxygen. The seat also contains a small survival kit & may be fitted with an automatically inflating raft for water landings. These will dangle underneath you as you descend. Ok, that’s about all I can recall off the top of my head. The ejection sequence is very, very short…pull the handle & you’ll be gone before you know it. In two-seat jets, the back seat goes first to prevent them from being burned by the rocket on the front seat. There is a sequencing lever in the jet that allows pilots to select if both seats will fire if any ejection handle is pulled, though…so you can select that each seat must pull its own handle. Useful if doing orientation rides for non-pilots…you don’t want them ejecting you, too.

Hello, Moon. It’s great to be back. Here’s a taste of what the Artemis II astronauts photographed during their flight around the Moon. Check out more photos from the mission: nasa.gov/artemis-ii-mul…

@jane_kihika Never.

This is for Mercedes and Lewis fans 😅 at what point will you let go of 2021? It’s five years already guys 😂

@DrChrisCombs How do you even do the maths that works this out. Twists my melon!

I love this perspective as well Really showcases how we are "catching" the moon with this trajectory

@joncoupland B for sure.

Which set of wheels? For me ... B

@F1BigData @SoyMotor "Street circuit" >> build a whole racetrack >> doesnt seem very street-y to me!

The Madrid street circuit is starting to take shape, specifically, the famous banked corner 📸 @SoyMotor

@ListerLawrence 28 years and counting.

I love photos like this of the same person keeping a car for 50 years. I wish I was that kind of person.

@RupertLowe10 Fucks sake 😂

I am delighted to release Restore Britain's first ever party political broadcast.

@OCDaboutCars 😂

A 'local' dealer has had a car for sale for at least 6 months now. £12.5k the whole time and they've finally decided to lower the price to see if that gets someone in. They've reduced it by...£40 This seems to be the new normal for a lot of dealers these days. Baffling.
