The high humidity in the morning made for some fantastic floofage footage. For any non-aviation geeks reading this, floofage, fluffage/floof is slang for the white clouds of condensation formed on a wing's upper surface by the low pressure air flowing across its curved aerofoil section. Fluff + puff + pooooof💨= floof.😁 You won't see floof in hot, dry conditions at ground level, but condensation trails are normal at high altitude where pressure and temperatures are low. You'll also see it around fast military jets performing high-G manoeuvres. Condensation trails are just long, thin clouds: hot exhaust and water vapour breathed out at 1,000°C into freezing cold air at minus 50°. Mmmm, frosty... London's almost at sea-level and is quite often wet, so low cloud, fog, mist and condensation are common in dense, moist air. Perfect conditions for wingtip 'ribbons' and floofage which is after all the same stuff that natural fluffy [floofy!] clouds ☁️are made of. You can also see floof form inside engine cowlings (another extremely low pressure area) as turbines are run up to speed before take-off if the weather's damp enough. A big jet's wings generate literally hundreds of tons of lift, so it's no wonder that any water vapour nearby gets smashed into condensation by the violence of the forces involved. It's easy to forget that the air's rarely still. It's swirling around all the time and just takes some moisture to make it visible. So why is floofage and condensation not always visible, even when planes are taking off on the same runway, barely a minute apart? Because the atmosphere isn't consistently dense or moist. It's moving in all directions all the time and in the UK at least is very rarely homogeneous: there are dense bits, rising bits, falling bits, still bits, dry bits, turbulent bits, bits blowing sideways - the whole thing is like a badly-mixed tin of paint 40,000' deep, full of lumps and swirls and bubbles. Even a block of air as small as a garage will be full of moving ripples and uneven patches of moisture. So floofage only shows up if a plane passes through just the right patch of moist air at just the right speed at just the right moment. Anyway, well done Robo-cam for tracking the planes through the fog and cloud this morning. On a less sensible note, I'm surprised TH-cam's conspiracy theorists weren't busy filling the Chat with Twilight Zone tales about the water-droplet condensation ACTUALLY being mysterious clouds of weather- and mind-control chemicals. Oh, yeah. Full of nano-bot brain parasites. [Joking.] Didn't you know? Wake up, people!! The government's using jet airliners to shape the weather, spraying tranquillizing chemicals from their wings and engines to make weird stuff happen in the atmosphere!! [Still joking.] As if airlines would spend a single penny hauling round gallons of secret chemicals when they're already obsessed with keeping costs down and mass to a minimum. If in doubt about the veracity of something, always follow the money. Airlines don't waste cash. I remember when they got rid of china plates and swapped metal cutlery for plastic knives, forks and spoons to save weight. And then they shrank the spoons and reduced the number of tines on the plastic forks from four to three🍴👀in order to save even more weight. Over a fleet of hundreds of planes travelling hundreds of millions of operational miles, every excess gramme costs fuel. So... Jets are releasing thousands of gallons of weather-control chemicals, are they? Yeh, sure, guys. Wear your tinfoil hats with pride.🙄 Meanwhile, back on Flat Earth... (🤭) ACTUALLY, the wing floofage seen today wasn't created by low air pressure. No, no, no. It was ACTUALLY a powerful psychoactive neuro-chemical carried on all jets and sprayed from tiny holes drilled in the leading edge slats. Yeah! ACTUALLY, leading-edge slats aren't deployed to increase the aerofoil's camber at low speed and generate more lift - that's just a cover for their REAL purpose, ACTUALLY, which is to make us all obedient slaves to Big Aviation and reinforce the ACTUAL lie that the Earth is a globe and not flat, ACTUALLY... [Yep. Still joking. I have to say that because TH-cam doesn't get sarcasm or irony.] Sigh. It's ludicrous, but some people really do believe this conspiracy stuff about jet airliners (ACTUALLY). You couldn't make it up - because you're normal. But conspiracy theorists do. I pity the phoools. They must have got heads full of floof.☁️👀
