Breakthrough in Air India crash probe as investigators back leading theory revealed in ‘gamechanging' video of disaster
INVESTIGATORS on the Air India crash probe have backed the leading theory about what went wrong after a "game-changer" vid showed the final moments in detail.
More analysts now agree that an emergency system was deployed as the plane went down.

A HD video showed a "protrusion on the belly of the aircraft", with a "little grey dot" beneath it.
Commentators say this is evidence of the Ram Access Turbine (RAT) deploying on the plane, which failed to climb more than 450ft.
Commercial airline pilot Steve Schreiber, known as Captain Steve, explained: "Many aeroplanes have it. It is just behind the wing on the right side of the aeroplane, there is a little door that holds it in.
"It looks like a little Evinrude motor, it's a little two bladed prop.

"The purpose is to provide electrical and hydraulic pressure for the aircraft on an extreme emergency."
Steve explained there are three things which could cause the RAT to deploy on a 787: "A massive electrical failure, a massive hydraulic failure, or a dual engine failure.
"But I think the fact the aeroplane is mushing out the sky gives the idea it was a dual engine failure."
What is Ram Air Turbine?
A RAM Air Turbine, known as RAT, is a small wind turbine fitted into planes which generates power in the case of emergency.
It will deploy if the main engine stops generating power for any reason.
When activated, the small turbine stick out from below the wing or fuselage, and harnesses the wind power caused by the plane's speed.
The airflow makes it spin round, in turn generating electricity which can be used.
This happens using a hydraulic pump or electrical generator linked up to the turbine.
A key feature of RAM is that is acts independently from the aircraft's engine and other generation means, meaning it can in theory be used to create power even when the main systems go down.

Trick to clean your house even faster with '30cm rule' as top Dyson whiz reveals common vacuum fail we're all guilty of
Click to share on X/Twitter (Opens in new window) Click to share on Facebook (Opens in new window) A TOP Dyson designer has revealed exactly how fast to move your vacuum cleaner – and going slower can actually save you time. It turns out that racing around your house isn't necessarily the best way to get the cleaning out of the way quickly. Sign up for Scottish Sun newsletter Sign up 6 You may have been vacuuming wrong your entire life Credit: Dyson 6 You'll want to visualise one of these during your next vacuum cleaning session Credit: Getty 6 The Sun's tech editor Sean Keach took a trip to Dyson's Oxfordshire HQ Credit: Sean Keach Vacuuming an entire house can be a bit of a nightmare, especially if you've got loads of furniture, carpets, and a dog or cat. So going fast can be tempting now that vacuum cleaners are often wireless and lightweight – just look at Dyson's impossibly thin new PencilVac. SPEED TEST I took a trip to Dyson's Oxfordshire campus where I heard from Dyson designer Jonny Gray, who revealed the exact speed you'll want to be moving your vacuum cleaner. "To be exact, about 0.3 metres a second is probably where you want to be in terms of speed," Jonny explained. That's a 30cm ruler, so if you imagine moving across one of those every second, you're getting it right. "I'm sorry to say that the slower you go, the cleaner your floors will be," Jonny said. Of course, he warned that you can also end up going too slow. The Dyson design whiz said you'll get "diminishing returns the more you go over it". So it's important to not go too slow or fast – and stick to the 30cm rule. "The IEC standards that we get are 0.5 metres a second," Jonny, Senior Design Manager at Dyson, told us. Watch Sir James Dyson unveil secret PencilVac, world's slimmest vacuum cleaner "But we have demonstrated that you get around 100% pick-up over the course of three passes with 0.3 metres a second speed." If you rush around, your vacuum cleaner will end up missing bits. And if you go too slow, you're simply wasting time – and it won't be worth the wait. FOOD FOR FLOORS Jonny, who works on vacuum cleaners at Dyson's gigantic Malmesbury campus, spends time trying to pick up all manner of difficult debris. 6 Dyson's senior design manager Jonathan Gray revealed the secret to vacuuming Credit: Sean Keach 6 The Sun was given a peek inside Dyson's debris cupboard, filled with commonly spilled items Credit: Sean Keach And he also told The Sun that Cheerios are one of the trickiest things for a vacuum cleaner to collect due to their size. But he warned that US-style Froot Loops are even trickier to collect. Dog biscuits are also difficult for vacuum cleaners to pick up, Jonny revealed. But the brainy Dyson designer explained that if you follow the 30cm rule, you should be able to get a "100% pick-up" rate – even during a nightmare Cheerio spillage. WHAT'S IN DYSON'S SECRET FOOD CUPBOARD? Here's what The Sun's tech editor Sean Keach found inside the Dyson cupboard... Porridge oats Rice Pasta Long-grain rice Nylon pieces Japanese sushi rice Japanese tea leaves Sugar Bread crumbs Finishing plaster Cotton wool balls Cheerios Popping corn Cat food Hair Tapioca pearls Froot Loops Dog biscuits Bicarbonate of soda Cat litter Picture Credit: Sean Keach Dyson's Lab includes a cupboard filled with different materials for testing with its vacuum cleaners. That includes porridge oats, British and even American rice, sugar, cotton wool, and cat litter. And they even have Japanese sushi rice and tea leaves, to make sure that the vacuum cleaners they flog to Japan are up to snuff.

All WhatsApp users unlock free ChatGPT perk inside app – but you'll have to enter special code to find it on your phone
WHATSAPP users can unlock a handy new ChatGPT feature directly within the messaging app. The popular AI platform was added as a free chatbot to WhatsApp at the end of 2024, allowing users to ask questions and start a conversation. Anyone can access ChatGPT via WhatsApp by entering a secret code. You simply need to add 1-800-CHATGPT as a contact. But today the feature gets an enhancement, creators OpenAI exclusively revealed to The Sun. ChatGPT on WhatsApp now has the ability to generate images. There are two ways you can do this. Either, ask for any image you want by typing it out. Or, you can upload a photo from your camera roll and describe how you'd like to transform it. Users without a ChatGPT account can generate one image per day, with the option to link a ChatGPT account for additional images. Those who link their existing account will have higher usage limits per day. It comes only a few months after OpenAI added shopping features to ChatGPT. WHAT'S IT LIKE? By Jamie Harris, Assistant Technology and Science Editor at The Sun I tried out ChatGPT's new image generation within WhatsApp and it came back with some fun results. I uploaded a photo of myself on holiday and asked it to turn the image into a cartoon. "Got it - I'm working on creating that image but it might take a bit," ChatGPT responded. "I'll send it as soon as it's ready." Three minutes later and it came back with the pretty cool image seen here.
