Its called a highspeed taxiway, you come off the runway part of the way down and slow down on the taxiway rather than clogging up the runway for the rather mundane task of slowing down.

Speeds up landing operations a fair bit.

The taxiway is to the left. The aircraft appears to be at the begining of Kai Tak's runway, note the arrows underneath her, so I think this Andy Mok bloke just got his English a bit back to front. It's taking off?

Look very closely at the markings immediately under the tail. It appears very much as if it is an arrowhead. Now if I recall at Kai Tak there was a displaced threshold, and arrows on the centre-line, are used to separate the start of the paved strip from the threshold. Therefore it looks to me as if this is in fact a photo of an aircraft starting its take-off roll and nothing to do with taxiing.

Anybody else care to comment?

I agree with Myt322. That's a runway the aircraft is on.

The aircraft's defenitely on the runway. No doubt from my side.

Strange that the photographer couldn't recognize that fact as he was litteraly standing right beside that plane.

Maybe he needs some lessons what is what

Was the photographer on a boat? I don't think you can stand there as it is the sea, or at least the edge of the runway.

The Kai Tak runway doesn't allow you to fast taxi, afaik, because you need to make a 180 degrees turn back towards the terminal, and if you are still running fast you'll run into the water.

Did anyone think that thats a WHITE runway light in the foreground there and NOT a BLUE taxiway light?????

Oh and I dont see any SPOILERS displayed if it is on rollout onto the highspeed taxiway turn off....

Thats a runway kiddies...

Another explanation is that it could be a slightly timed exposure.

Yeah those are definately the arrows found in a displaced threshold. He's gotta be on the takeoff roll.

If it is a displaced threshold are they supposed to remain at low power until reaching the runway? Maybe he is anticipating just a bit.

Hey I guess he can be forgiven. If flight attendants can tell me, a hundred feet from the jetway that "we are still on an ACTIVE RUNWAY" I guess this is not too serious.

Aircraft can start the takeoff roll as far back in the displaced threshold as they want, but they can't land on any portion of the displaced threshold. Exposure time is probably less than 1/50 of a second. Also, I don't think the plane was going over 30K, especially that early in the runway.

I'm surprised you asked Slamclick, was it different back then when you flew?  Confused

How, exactly, can any of you tell how fast the aircraft is going? With the darkened skies, the aircraft could be traveling at a normal taxi speed, and the camera was moved, giving the blurred effect of the background much more than it would had it been a bright sunny day. Regardless of whether it was a taxiway, runway, freeway, or sidewalk.


There are 3 simple rules for making a perfect landing every time. Its a shame that no one knows what they are.

I think you probably just understand more about how camera exposure works than most people.

In a relatively dark exposure like this, the photographer would probably be shooting with both a fairly long shutter speed and as wide an aperture as his lens will allow. The former will introduce motion blur and the latter will result in background blur (even if the camera's stationary). There's a bit of both in this photo.

You can't tell how fast this a/c is going from this pic at all. It may be at the beginning of a takeoff run, or taxiing, but it could still be going five knots for all anyone knows.

Well, from what I remember of Kai Tak, the guy should've started his takeoff roll because IIRC most planes initiate takeoff roll in the displaced threshold, sor of where the JAL plane is in the airport overview. If you look at the FedEx plane it is right about where the yellow crosses are. As far as I can remember, he would have just begun rolling.

So I guess the photographer was not on a boat but was on one of the buildings right next to the runway. I forgot there were a few buildings that way.

Exactly. The FedX MD-11 is in the same location as the 747 in your picture. The FedX MD-11 is not taxing, it's starting its take off roll...!!

Quoting Apollo13 (Reply 23):

I believe it has something to do with the ground not being hard enough to sustain aircraft landing on it with high weights. Maybe the land was once swampy etc..

Aircraft can take off from it though using the full displaced thresh-hold.

Someone please feel free to correct me.
