Could This Be A DC-8?

Hi all!

Can someone confirm if the wing in the photo below is a DC-8 wing or not?

The photo is taken in Copenhagen or Hamburg in 1972 or 1973, most likely in a Loftleidir Icelandic or an Icelandair aircraft.

Thanks in advance for any help!

Looking at other DC-8 pics, the top of the pylon is straight, not curved (on JT3D-engine a/c anyway).

How about a 720? With JT3Cs, not a 720B.

Definitely a DC8-50 or 61... I looked at the top of the #4 engine nacelle.
A 707 or 720 nacelle and pylon look different, with or without a T/C...
I used to fly DC8s... so I bet a beer on that one. Polar Bear brand...

All the best, Asgeir... I had an Icelandic friend with same name, great pilot...

That's not the top of any DC8 wing. Vortex generator's ??? Where are the fuel tank panels ??? I don't know what plane that is but its not a DC8.


Next time try the old "dirty Sanchez" She'll love it !!!

I second the opinion that the airplane is definitely not a DC-8. Vortex generators of that type would usually be on a Boeing designed airplane.

You, gentlemen might very well be correct... vortex generators...
I looked at the nacelle and the pylon, does not look like 707 or 720 to me...
So I assumed it is a DC-8...

No excuse for this old fart here, I know both planes very well, I flew both.
But it looks like I lost my bet... and gracious about admitting it.

Take a look at the wing in this photo, which one guy in the Aviation Photo forum linked to in a thread I started there on the same subject. It looks very similar (count the screws where the pylon goes into the wing - they are 13 on both photos).

Dear Asgeir -
xxx
That is definitely a Boeing wing...
Clue - inboard and outboard flaps...
Inboard aileron (with balance tab)...
xxx
The DC8 has single unit trailing edge flaps
With a "gate" aft of the inboard engines.

I have to put my glasses on my nose to look at all these pictures...

On DC-8s with P&W engines the top line of the pylon is about straight. This pic is clearly not any DC-8 from -11 thru -63.

On Convair 880/990 the top edge of the pylon is straight or curves the other way. They're out too.

On 707-120/-220/-320/-420 the pylon reaches the front end of the nacelle. On 707-120B/-320B and 720B the pylon reaches the front end of the nacelle, or if it doesn't the top line is straight. Forget about them.

That leaves the JT3C-engined 720-- and maybe the KC-135?

Hi guys.

The three 707-3 pix below show that all 3 aircraft have a double row of vortex generators (VG's) behind the inboard engines. Does this have any bearing on whether or not the right wing in Asgeirs's original photo belong to a 707-3 series airliner?

Regarding engine pylons, the 707 in the first photo clearly shows that the engine pylons reach the front of the nacelle. The second photo looks like it has 2 different types of pylons on it's engines.

707-351.

Couldn't the picture (seems to be a diapo) be "misprinted" (turned over)? Aren't we looking in fact to the left wing?

Big thanks to all of you guys for your help! Your input has been very interesting and helpful.

The conclusion seems to be that this is a 720 with JT3C engines. By "interrogating" my family, I have been able to pinpoint the time the picture was taken to the end of May 1974. All this fits perfectly with the information I got from the Icelandic Aircraft Database (http://www.cl44.com/caa). Air Viking only had one 720 registered at that time so I think I can be pretty sure that the photo is taken onboard TF-VVA, A Boeing 720-022 (cn 18082) constructed in 1962. I am told that there was some sort of a strike going on at Copenhagen Airport so the flights were operated to Hamburg. Passengers were transferred to Copenhagen and back in busses.

Here is the only picture I could find of the aircraft, taken from the Icelandic Aircraft Database site (It's not possible to link directly to the page where the photo came from, so I copied it to my site instead and linked to it from there).

AH-HA Look at the end of the #3 pylon fairing. I think that is a yellow Boeing life raft fitting that's on a lot of Boeing wings.... I'll bet it is a B720.

It is for sure a 707 wing because of the two rows of (squared) vortex generators.

Also the pylon of the number 4 engine has this gracious shape that extends from the wing almost to the nacelle, while on the DC-8 pylon went from the wing to mid section of the supported engine (except on the later models such as the -71, in which the size of the bigger engines made the pylon go almost all the way to the tip).

This is a 707 wing. Check the nacelle and pylon. Compare it with the picture of the thread. Observe the vortex generators near the root.

The following is a DC-8 (series 10 - 60) engine. Check how the pylon goes straight down the center (2/3rds) of the engine. Observe the lack of V. generators:

And finally, this one is of one the later models of the DC-8 family, with big fan engines.

Fly727 you are right, except for the series 62/63. The pylons are mounted under the wing, like the ones with the -70s, in order to reduce drag.

More proof that it is a 720/707-100:

The escape route painted on the wing (in the photo above) routed you towards the inboard flap (and away from the split flap shown on Air Viking) instead of towards the most inboard "filler" flap on the -320 airplanes (such as on Avianca above).



This plane is built to withstand anything... except a bad pilot.
