I had to post this...I thought it was pretty darn impressive and elegant. It truly looked like a albatross or something.

They fly a lot better with no passengers and a much-reduced fuel load.

Should have rolled it like the Dash 80 back in 1955.

Wow, that thing can fly like a crop duster. The pilot really knew how to make it dance. Of course, I agree, with no passengers and low fuel, it's gotta be much easier.

They got in trouble for flying a bit too flamboyantly with their quarter-of-a-billion-dollar aircraft in front of the spectators at Farnborough.

Oh man, I would LOVE to be a passenger on that plane when it did those maneuvers.

After Habsheim http://en.wikipedia.org/wiki/Air_France_Flight_296 there are no passengers on air show aircraft. It's far more fun anyway to be in a light aircraft and for aerobatics, you get to pull more G :)

I'm in complete agreement on Boeing getting in to trouble with that display, that bank was applied too low and there was a significant risk of a wing tip impact. The roll centre is the fuselage, not the wing tip.

For spectacular large aircraft take off, my favourite is the Vulcan, especially the big wing-over http://youtu.be/X98ZnZs-2ds
The Vulcan is a big 4 engined cold war nuclear bomber capable of carrying 21000lbs of conventional bombs. With no bombs and only a splash of fuel in the tanks then it goes up like an angel returning home. With the low clouds that day they needed to stop climbing quickly to keep under the cloud base. Pushing forwards on the stick would have resulted in a negative-G manoeuvre that the aircraft was not designed for, whilst a wing-over is a positive-G manoeuvre throughout so whilst it looks spectacular (especially when flown by something as big as a Vulcan) then it is safe for the airframe.

Still should have rolled it, followed by an Immelman. Both maneuvers can be executed at +1G constant with no additional stress to the airframe. Given the "Fat Albert" launch seen in both vids, she's certainly got enough thrust when flying light.

I've long suspected that modern airliners have flight qualities and capabilities that go far beyond what we see while cattle in the can.

With the 787-9 being made of mostly carbon fiber I would like to see other big airliners try what it can do with a equivalent fuel load I bet we would see some wing dragging.

I watched another video of the 787-9 taking off from a stop with only one engine. I am sure it was not fully loaded since it was from a dead stop and not a rolling engine failure halfway down the runway or just after liftoff when most flame outs and bird strikes happen.

It was impressive.

I also finally looked up what the exhaust on the tail of a 747 and other planes do. It is a small turbine powerplant to power the plane on the ground when the engines are not running.....also I am sure in flight it is a alternate power source in the redundancy system. It saves the airliners a lot of fuel costs when the planes are on the ground.

The new 747 is a beast and took off breaking its load record with 1,010,000 lb take off weight.

I'm still trying to wrap my head around the fact that someone thought it was worth spending a pile of money to keep a 55-year-old retired bomber flying at airshows. They're still performing that maneuver with newer aircraft. Here's the 65-year-old chief test pilot in one of Airbus' A400M Atlas prototypes:

P.S.: It's also surprising, given that the planes fly the same show each day, that Airbus' TV camera crew missed the shot so frequently.

Why do people willingly pump cubic dollars into keeping WWII warbirds restored and flying? Take off the engineer hat every once in a while and just revel in the sheer aesthetics of XH558 pulling a maximum takeoff or a flock of P-51Ds coming over the field for a low pass at 400MPH with their throttles pushed through the gate and their Merlins howling. There's art and beauty in both and there are times when that is all that is needed and damn the costs.

Not sure about you, but I completely understand why a young Christian Bale reacted as he did in "Empire of the Sun".

I was just thinking that it costs orders of magnitude more money to fly a Vulcan than a P-51. You don't see anyone flying a B-36 these days, but this Vulcan did perform at Farnborough this year.

Yet many people are willing to pay that bill to allow others to see XH558 take to the sky once more. A pure utilitarian fail, but a big aesthetic win.

Oh, and the USAF made sure that there wouldn't be any airworthy B-36s after their trip to the Boneyard.

The fact that it's 55 years old and doing maneuvers that newer aircraft show off is why it is worth it. What they are now designing with millions of dollars worth of computing power was being done with 10 cent slide rules back then. Sure the cost seems high but then you look at something like Jay Leno's garage of classic cars and the price tag on the Vulcan seems like a deal. They aren't the only ones flying around vintage jets. Take a look at the Snowbirds, those Tudors are extremely underpowered, well past their expected airframe life expectancy, the newest of the squadron hails from 48 years ago and we're never designed for acrobatics.

Personally I wish more older jet aircraft were kept in airworthy condition for air shows. It's one thing to read about the Concorde, Blackbird, F-14, Voodoo's, F5, F-104, etc, and another to experience them in flight in all their glory. They are a testament to engineering when designing an aircraft didn't take over a decade to get into the skies.

They also use material that change their shape depending on temperature for the engines to optimize airflow for cruising or takeoff/landing.

Totally agree on wishing there were more of the old jets still flying. It's near criminal that not only did they ground Concorde but they drained fluids so they couldn't be put back in to flying condition without basically rebuilding from scratch.

The Vulcan is a bit special, it's a big bomber but with the huge delta wing it flys like a fighter in terms of manoeuvrability. It actually has a fighter stick rather than a bomber control wheel. Also the noise is truly epic, featuring an intake howl at low airspeed and high power as well as literally ground shaking noise out the back. My father worked at British Aerospace at Filton in Bristol and there was also Rolls Royce on the airfield. The "family day" airshow had everything - all kinds of prototypes, Red Arrows, F-111s (both serviced there), trips in Concorde out to the Bay of Biscay to go supersonic; but the display by the Vulcan was always by far the most memorable. I remember it doing a Go Around at about 25 ft, shaking the ground and then just climbing up through the clouds. As it went through 10,000ft a BAE146QT took off in front of us, we couldn't hear it over the noise the Vulcan was still making.

Best thing I ever did was taking the chance to fly a small Pitt S-2A on an acrobatics session. Not only as a passenger, but actually having control. First the pilot showed me the maneuvers and we talked a bit, then I got to fly, not only predetermined maneuvers, but doing them pretty much as I wanted. That said, didn't pull more then 5.5G or so, but doing a double loop with double roll in one go is a big treat for any enthusiast. That said, after having flown flight sims to and fro for 20+ years, I was surprised how well it translated to flying for real. The instructor also said it is quite a clear difference since people not used to it sometimes have a hard time getting the controls and instruments. What you don't get is the G's of course. Wasn't a problem for me being relatively short and not that thin.

So anybody interested in it, go do something like that, it is AWESOME!
