And a complete spoof - I'm no expert but pretty sure that the first thing you would get on turning a jet airliner upside down is an instant rapid plunge downward of several thousand feet, or in this case about a hundred feet before the ground intervened!

Yes, I believe they frequently have asymmetrical aerofoils (get me!) so they fly the same level or inverted. Invert an airliner and once it's upside down, all the aerodynamics that were forcing it upwards start forcing it downwards instead.

It's a fake

As for whether flying upside down is POSSIBLE in an airliner... it should be in theory. After entering the roll, you'd have to press forward/down on the controls, as if you were performing a dive, in order to keep the nose up. But of course an airliner isn't designed to be flown upside down, and doing so might place unusual stresses on the structure. Modern planes have software preventing the pilot over-stressing the plane, so in practice it might not be possible.


There are some accounts of airliners performing barrel rolls... usually accidentally, but at least one intentionally, famously in a prototype Boeing 707 over Seattle.

Well yes. The aircraft does appear to have no windows.. Give away.


The point was that it was never claimed to be a stunt.


It was mearly for intertainment value.


I bet you lot call out the punchline and heckle at a comdey night.

Fair enough. Yeah it freaked me out when I first saw it too.


The other giveaway was the passengers disembarking - from a completely different plane - in clear weather!

No. It depends on the angle of attack, as long as air is moving faster over the top of the wing there will be lift and the plane will keep flying.

Isn't lift caused by air flowing faster under the wing and slower over the top? Pretty sure that's how it works. So if the wing is inverted, the air will be flowing slower under the groundward side and faster over the top, pushing it down?


Mind you I'm an English graduate who doesn't really understand why electricity doesn't fall out of empty sockets, so could well be wrong!

Rendle, sorry I have been lazy and copied this:


Upside-down or right side up, flight works the same way. As you stated, the wing deflects air downward. When inverted, the pilot simply controls the the pitch of the aircraft to keep the nose up, thus giving the wings sufficient angle of attack to deflect air downwards.


It's less efficient and in a light air craft it requires full power.


It would mean pointing the nose towards the sky. Hope that makes some sense.

    • What was he doing on the stage at Glastonbury? Or on the stage at the other concert in Finsbury Park? Grinning like a Cheshire cat whilst pissed and stoned 20 somethings on the promise of free internet sung-- Oh Jeremy Corbyn---  What were his policies for Northern mining towns with no jobs or infrastructure? Free Internet and university places for youngsters. What were his other manifesto pledges? Why all the ambiguity over Brexit?  I didn't like Thatcher, Blair or May or Tony but I respected them as politicians because they stood by what they believed in. I respect all politicians across the board that stick to their principles. Corbyn didn't and its why he got  annihilated at the polls. A socialist, anti imperialist and anti capitalist that said he voted for an imperialist and pro capitalist cabal. He refused to say how he'd vote over and over again until the last knockings. He did so to appease the Islington elite and middle class students he was courting. The same people that were screaming that Brexit was racist. At the same time the EU were holding black and Asian immigrants in refugee camps overseas but not a word on that! Corbyn created and courted a student union protest movement that screamed at and shouted down anyone not on the left . They claimed Starmer and the centre right of labour were tories. He didn't get elected  because he, his movement and policies were unelectable, twice. He turned out not to have the convictions of his politics and died on his own sword.    Reform won't win an election. All the idiots that voted for them to keep out Labour actually enabled Labour. They'll be back voting tory next time.    Farage wouldn't be able to make his millions if he was in power. He's a very devious shyster but I very much doubt he'd actually want the responsibility that governance requires.
    • The purge of hard left members that were part of Corbyn's, Mcdonnel's and Lansmans momentum that purged the party of right wing and centrist members. That's politics. It's what Blair did to win, its what Starmer had to do to win. This country doesn't vote in extreme left or right governments. That's partly why Corbyn lost  We're pretty much a centrist bunch.  It doesn't make it false either. It's an opinion based on the voting patterns, demography and statistics. Can you explain then why former mining constituencies that despise the tories voted for them or abstained rather than vote for Corbyns Labour?  What is the truth then? But he never got elected!!! Why? He should have been binned off there and then. Why he was allowed to hang about is an outrage. I hold him party responsible for the shit show that we've had to endure since. 
    • Depends on what the Barista says doesnt it? There was no physical confrontation with the driver, OP thinks she is being targetted when she isnt. These guys work min wage under strict schedules so give them a break unless they damage your stuff
