My sister is working on this. I saw the 747-8 and went inside it last night. Not a whole lot to see. Feels like just another plane to me. The link has an interesting video where they show them actually dragging the tail of the plane on the runway during one of their tests.
Wow - that's cool! [thumbsup]
Lower takeoff speed = higher angle of attack to produce the same lift.
I like the GE engines on that thing.
The tests that they put those planes through are amazing!

I think they filmed that last plane landing this december on long island.
It takes a lot to make me concerned about my continued wellbeing, but that flight had me worried.
@ OP - WOW that's awesome!

Reminds me of a landing into Lansing MI over 30 years ago.
I was watching out the window and the runway was straight ahead.
It was terrifying.

Had one like that coming into Burlington, VT in the winter in the mid-80s, with the plane crabbing hard into a really volatile crosswind, with lots of small-cell up & downdrafts. The most memorable part was when we hit the runway and rolled to a stop, a hundred or so people finally exhaled. The woman next to me used her pent-up breath to claim loudly that she was going to write a letter to the airline complaining about the pilot, as that was the WORST landing EVER!
At that point, fortunately, her life was the only one that seemed in any particular danger.

I was on a Gufstream 4 in the late 90's that did one like that coming into the Azores. I think they said the crosswinds were at 47 knots with gusts. It was a pretty smooth landing and everybody gave applause when it was over.
Dumb question: do the rear wheels turn at all, so that they can land tracking straight while the plane is angled?
Im out on a limb here, but methinks no.
Didn't look like it when I was standing there in person.

You are correct.
If you watch closely you can see the nose kind of snap to the runway after touchdown.
Then the pilot lets the nose wheels touch.
You think they increase/decrease thrust on one side to help steer it in (like on a boat?)

To the best of my recollection only the C-5 Galaxy has rear steering wheels, but they are not steerable for landings.

I think they stick their heads between their legs and kiss their asses goodbye. :P
Seriously, I have no clue how they do it. I have first hand experience telling me they're good at it though.
I was thinking they might have the rear wheels designed to track kinda like a shopping cart for the crazy landings. Not so much actively steering them, just locked in totally straight for taxi mode, and shopping cart style for the crazy cross wind landings. If there isn't any kind of system like that, then those pilots have incredible skills and balls of steel (unless they are women, in which case they would have... I don't know... balls of steel.) I know planes are very different from motorcycles, I just can't help but see those landings and think about a motorcycle high-siding. Surprised the plane doesn't hit wing or at least wiggle around quite a bit.
Please someone find a video of a plane highsiding. . .
I used to do it all the time in a small Cessna, its really no big deal. Just dip the one wing down (the one into the crosswind) and make sure the plane is flying straight down the runway. After you get the wheel down the plane just straightens itself out. I guess its pretty much the same in a large plane.

They just run the conveyor in the same direction the plane's traveling.

Be nice.

The B52 is the only plane I know of that has that system. There are probably more.

Its all rudder
edit - to clarify its usually a mix of control surfaces, a bit of cross controlling rudder coupled with some dipping of the wing into the wind, usually pilot preference.

That's because the B-52 weighs as much as a small country.

Wow. I'm guessing they had to replace most of the seat cushions on those planes afterward.
Does anyone recognize the airport at around 1:40 in the video? Looks like Hong Kong to me - I've landed there only once (as a passenger), but it struck me as a pretty challenging approach even in ideal conditions. Kudos to the pilot in that one and all the others in that video!

Bet the pilot about messed his shorts on that landing!!

Boeing 777 Crosswind Landing Cathay Pacific Hong Kong Kai Tak Airport 香港 å•Ÿå¾·æ©Ÿå ´ (http://www.youtube.com/watch?v=dd9NM9vsGD8#normal)
Boeing did quite a few crosswind test landings of the 777 when I worked at the airport in Reno in the mid nineties...that airport often gets high winds coming off of the Sierras perpendicular to the runway. It was very cool to watch. [thumbsup] The cabin of the plane was full of computers, work stations for engineers, and large water tanks so they could shift the weight balance for the flights. United also used to do training landings at Reno on ocassion.
