Probably smoother than any of the landings where I've been a passenger Grin

A different angle here

That landing looks smoother than a Kashmir codpiece. I am a bit jealous, puts most normal landings to shame that I have experienced Grin

A superb bit of work, buy that pilot a pint! God knows he deserves it!!!

Now!!

can someone tell me WHY a landing gear could do such of FAIL ? I mean this could be end as a tragic
I could swallow that 1 of the gear fails BUT the three all gears system,¿?¿?¿? Don't they have a back up like manually drop the gears or something ,this is a 767 for Christ sake ,one of the modern airplanes ,.. Undecided

I'm imagining the bystander conversations.
Bob:HEY LOOK, There's a plane landing without a gear and it might amount to a terrible crash and the passengers may need our help.
Billy: Quick get a camera, Grin

Most people think that flying a plane is dangerous, except pilots because they know how easy it is.
Arguing with a pilot is like wrestling with a pig in the mud, after a while you begin to think the pig likes it.

The 767 does not have a manual system to let the gear down if the primary fails. What it has is an electric backup that trips the up-lock boxes to go into free fall to extend the gear. It would appear and I am only speculating that the aircraft suffered a multi system failure. I would guess electrical on the initiation side of the hydraulics and then on the electric up-lock trip circuit. The 737 system is much simpler, a small panel beside the co-pilot with three cable pullers, one for each leg. A direct link to the up-lock boxes from the cockpit.........KISS....................Keep It Simple Stupid!!

Shocking. And to think they've progressed to be the worlds leading commercial aircraft company. Then again, that said, an ANA 737 did almost do a barrel roll in September after a mistake was made using a piece of switchery on a 700/800 that was identified as potentially fatally unsafe on a 300/400 20 years ago...

VC10 has 3 levers in the radio bay to freefall the gear under gravity, one for the nose, and two for the mains, so they could all be lowered if necessary, whatever system failed.

It also came with a man to lower them... Wink

And the third backup is the skidrails to keep it from falling apart when you land on the belly

Sure it's scary, but I wish people would give us engineers more credit. We think of every possible (survivable) failure and make sure you survive it. The guy I share a cube with designs doors, and about 80% of the stuff he mentions sizing it to seems like it would NEVER happen, but we design it to withstand it anyways.

The problem is, Jake, I have been working on stuff that engineers have designed for the last 24 years. Generally most jobs start with, "what Muppet living in a cube designed this and put it here" Angry

Oh so true! Although I do not work on aircraft (im an auto mechanic), we always get in these USAF engineers with some problem in their car that think they know how a certain system works (or should work) just because they helped engineer the nosecone on a C-130.

I so want to ask, "Oh, do you work for Honda as an Engineer?" Oh, you dont... so stop assuming you know how things work. You many know a C-130 in and out, but this car of yours is no C-130. lol No disrespect to any engineers... but if you bring me your car, you obviously do not know how to work on it, or else you would have already found and fixed the problem! Ok, a little bit of a rant, sorry... Im done! Grin

To be honest I think that's a far worse situation landing with no gear is actually much safer than landing with only one of the main gear stuck down because you have to try to stop the aircraft spinning off to one side and you put a uneven stress load on the aircraft.

Landing with no gear is technically the same as landing with all your gear, you just have to make sure you hit slightly softer and with the plane dead straight down the runway.

Still very impressive though!

Yes we do Jake, it seems though there are 3 widely different opinions on an aircraft. Mechanics always say whatever plane they work on is a POS (specifically military mechanics), pilots like to say their plane is the best thing. Engineers who design the thing can be worse than pilots in regards to thinking their design is the best. BUT most engineers that work on a plane design do not work on designing the plane. They work on sub components or even sub components of sub components and they dont know jack about the aircraft.

We engineers do have methods to our madness, anyone doubting them I ask to try your hand at going through an aero engineering curriculum. You will learn real quick we learn a LOT.
