When I was a child, we always discussed what plane is much more beautiful and more efficient: B 707 or DC 8.
What do you think?
I for myself prefer the good old 707. One of the most beautiful planes ever built.

QF's 707-100s were called V-jets because they were equiped with turbo fans. V stands for Vannus which in latin means Fan

What's interesting is that the 707 completely won the sales battle, setting Boeing up for 30 years of domination and Douglas to eventual ruin.

Well, that's not the interesting bit. The INTERESTING bit is that the DC8 is the one that endured, whereas the 707 is much more scarce these days. I know it's partly cos the 707 couldn't be as easily reengined but there are still P&W powered DC8s, the original powerplants.

Any thoughts? Anyone seen JETPILOT lately?

Thanks a lot, Marara! I asked couple of people, even "older" flight-attendants from QF. Nobody had a clue!

Part of the reason the 707 sold more than the DC-8 was that Mr. Mac ordered the DC-8 line to be shut down, arguing that every stretched-8 sold was a DC-10 sale lost.

I got to fly on both numerous times in my youth and loved them both. I have a small preference for the DC-8 looks wise, especially the -62 variant, but both were great.

The main reason that the 707 won the sales battle was the Dash 80 prototype. While Douglas was building DC-6s and DC-7s in the 50s, Boeing was demonstrating the Dash 80 which first flew in 1954. Plus Boeing was offering several lengths, the -100 and -300 variants and the 720. This gave Boeing a lot of marketing and sales momentum that Douglas was never able to overcome, even though the DC-8 entered service only a year or so after the 707. The stretched DC-8s didn't enter service until 1967, by that time the 747 was already on the horizon.

Here in Miami we still get to see the old birds coming in as freighters, but most are DC-8s.

cheers, Ralph

I flew both the 707 (all majors versions) in my PanAm days, and the DC8 with ONA during a furlough period from PanAm. I have to say that I did prefer the handling of the 707 as compared to the DC8...
The 707 was a little faster in cruise (we used Mach .82 generally) whereas the DC8 was normally cruising at Mach .80 - Should you compare both types further, here are my general opinions -
With the 707-320B/C, compared to the DC8-50 and -61, the 707 is a winner for performance, capacity was equal, except that the -61 could carry larger amounts of passengers. The 707-320C with extra emergency exits, just aft of the wing was certificated for 219 passengers, while the DC-8 was limited to 189 passengers (the -61 was certificated for 259 passengers)...
When the DC8-62 and -63 became available, these were finally a match for the 707-320B/C. The DC8-62 performed and carried as much as a 707, and the -63 with the increased takeoff weight was an outstanding passenger or cargo aircraft. I got the chance to fly the DC8-73 a few times, that was an outstanding airplane. I have a friend that flew a DC8-72 for Aramco, he did love that airplane. Wish I had flown one of those to enjoy...
Airplane "looks" - I could not care less, for me is "how good they fly" and "what can they carry and how far" is my yardstick...
The 707 was much smoother to land than the DC8... The 720B, the short body 707, was a race horse, a real "sportscar"... What "bugged" me the most with the DC8 was the low gear and flaps extension speed (230 KIAS) and being unable to deploy spoilers in the air to use them as air brakes. In the DC8, our speed brakes were the inboard reversers, which were drastic and uncomfortable on passenger flights, so much that it was recommended to advise the passengers about the noise and vibrations...

Unlike some pilots, I want my aircraft to look good. So here are a few of my ideas about the two aircraft:

The wing sweep and tail of the 707 look better to me than the DC-8. I also prefer the look of the 707's windows- except for the windshield. The "8" has the center windshield corresponding with the overhead console. This is pretty nice. The Boeing just has a post.

Douglas's nose is preferable to me with the exception of the nose intakes which I'd rather see back some. But most of the DC-8 engine and pylon arrangements appeal more to me than do the 707.

As far as how they fly? The Boeing is faster and more precise on the controls. The DC is perhaps a beefier plane for heavy loads.

Lots of Nostalgic memories of many times on both birds...but I think I enjoyed the take-off performance of the DC-8-62...I recall taking a few from ORD-BDL in the late 70's...great climb out with such a light load of fuel.
As I recall, there was a time when UA flew the 62 nonstop JFK -HNL in the late 60's , early 70's.

I also loved the whine of those pratts on the 707's....gee I miss all those days!

In appearance, I prefer the 707 over the DC-8.

As a young boy flying aboard both types, I usually preferred the 'eight because of the large windows, which were much easier to look out of. The only drawback with the latter was when some airlines changed interior configurations, resulting in a large blank area between the windows, meaning that I had to crane my head far back or forward when the seat back was fully upright during take off and landing. The stretch 'eights had very nice interiors; I never did care for the reading lights in built into the Palomar seatbacks of the earlier models.

I seem to remember a mention that as the 707s were retired from pax service that Uncle Sam was buying them up as spares for all the variations they have in the services. This left too few available at any time to make converting it to Cargo service expensive. While the DC-8 had no such competition for its post-pax life, the cargo companies could get enough of them to make them worthwhile in converting to freighters. Especially when they re-engined them into the -7x series.

To begin with, I would first like to state that I consider this topic to be slightly flawed, as the 707 and DC8 were not the only competitors for long distance aircraft in the early 1960s. You also had the Vickers VC10, which was from many accounts a superior aircraft in terms of comfort, performance etc, and failed only due to BOAC's preference of the 707-420. Then there were the Convair CV880 and 990 aircraft, which were competitors in the field, even if their products did not precisely align with the DC8 or 707. Also, there was the Comet 4, and behind the Iron Curtain, you had the TU104 and the Ilyushin IL62, both of which filled long-distance jet transport roles similiar to their competitors in the west. So perhaps a better topic would have been "Which Early Long Distance Jet Do You Prefer."

That said, of the DC8 and the 707, I prefer the 707. It was a better-designed aircraft. The air intakes on the front of the DC8 were actually put in at the last minute because Douglas forgot to design a cooling system for the avionics equipment in the nose (this insider information coming from a TWA captain who was a good friend of mine). The 707 had an incredibly strong airframe, a beautiful interior, and an elegant external apperance. It's main deficiency was the fact that it could not be stretched efficiently due to the high wing sweep, but this was a blessing in disguise as it paved the way for the equally revolutionary 747.

Speaking of 747s, B747Skipper made an interesting comment: "The 720B, the short body 707, was a race horse, a real "sportscar"...

My aforementioned friend who was a TWA captain himself made comments to this effect. He described the B720B as being like "rocketships" and as having been tremendously overpowered. Apparently the B720A was more of a mundane aircraft to fly thanks to its less advanced turbojet engines...

I've always wondered why some 707s and 720s didn't have the tail antenna. Some recently posted pictures on this site show from the late 70s show AA 707s without the antenna. I know the very early models (non fan jets) didn't have it but it seems some 707-120B and 720Bs didn't either. Does anyone the reason?

The antenna at the top of the fin on the 707 or 720 is a HF antennas, only used for communications overwater / overseas. Airplanes which were used on USA domestic routes did not have the HF antenna. All the PanAm airplanes had the HF antenna but some TWA airplanes (-120 series) did not. The United 720 had no antenna, but all 720 used by other airlines overseas had them.
The inlets under the nose of the DC8 are actually inlets for the 4 turbo compressors (providing warm or cold air and pressurization) and were not "vents" for avionics cooling...
In the 707, the turbo compressors were located on top of the engine inlet, at the base (or nose) of the engine pylon. Some had only 2 T/Cs, which were on the inboard engines, some other had 3 T/Cs, the third one being located on top of the #4 engine... The #1 engines were never fitted with any T/C, no matter what airline and option it was... Those of you who like to verify and be picky, go and look at pictures of the 707s and 720s... I assume that A.Net probably has tons of them... I never saw a 720 with 3 T/Cs, they normally had only 2 T/Cs...
Back in my old days I used to be an expert about 707s, and knew all the differences.  Big grin
Nowadays, I must try to remember - old age does that to you...

I finally know why they antenna was there. Thanks 747Skipper! What you say about the DC8 nose inlet makes sense because I notice on the reengined DC8-70s those inlet were changed.

i like the 707 better. the most attractive feature is the commonality (at least in the cockpit) with the 727 and 737. i'd love to be able to have the following three to my self: 707-300, 727-100, 737-200.

Dear Invicta -
Indeed you are correct, on the 70 series, with the CFM engines, the airplane air conditionning / pressurization uses air cycle machines (ACM) rather than T/Cs...

Friends, do you know why a 720 got called 720...?
Well, originally, it was supposed to be called 707-020... this indicating that it was to be yet smaller than the 707-120... Then, came United order - nearly 30 airplanes... but there was a problem...
United had ordered DC-8s (rather than the 707), and the board of directors were not convinced that major stockholders would be happy that after first ordering DC-8s, they would admit that the 707 was a better airplane...
The sales contract got concluded - and Boeing agreed to United's insistance to change the designation into "720"... so United got 720-022 airplanes... "a different airplane from the 707" as justification for stockholders.
The funny thing is, AA had ordered 707-123s initially, were happy with them, soon ordered the 720 as well. But AA considered both 707 or 720s as the same type airplane, even painting "707 Flagship" on the side of their early 720s... after all they are just lightweight short 707s... and to passengers, both airplanes looked alike anyway...
The above stories come from a book "Boeing 707" by Terry Morgan Sr. (ex captain with Braniff)

Great story, Skipper. I had always wondered about that break with Boeing's modern naming conventions, although I suppose back then, it wasn't a naming convention quite yet.

The 707-120's and 720's had two turbocompressors, in the inboard engines. The 707-320B/C had three turbocompressors, both inboard engines, and one outboard. As I remember it was the right outboard that had it but it may have been the left one. I don't recall whether the non fan 320's or the RR powered 420's had two or three. I only flew on a non fan 320 a couple of times and never on a 420.

The HF antenna was for the CRAF program. United and American 720's did not have them. Neither did TWA's 707-131B's. I believe all other aircraft in the 707/720 series had them.

The DC-8 was slightly slower in cruise than the 707, at least in the JT-4 powered airplanes. Some Pan Am pilots called the Doug the DC-Late. The DC-8 is a beefier airplane. Most 720's were retired early because they needed major work. For example, United considered re-engining their 29 720-022's but they also would have had to reskin them, after less than 12 years of service.

As far as comfort, the early 707's had a common Boeing deficiency, not enough tail. They would yaw quite a bit. As a kid, the only airplane I ever got sick on was an early TW 707-331.

They later added height to the tail, and a stabilizer under the tail of the fuselage to dampen the yaw.

The USAF purchased most of American and TWA's 707 for the KC-135 program using the JT-3D engines and wings. That did not take the 707's off the market. They used them because they were cheap. There was little market for them. The 707 could not be stretched because they were too low to the ground. Stretched, they would have needed a taller gear to avoid tail strikes on rotation. The Eight has outlived the Boeing because its a sturdier airplane. There were plenty of 707-320C's with cargo doors already installed, reinforced floors, etc, and ready for cargo use, with no modifications. Few of them are still in use.
