I know Pan Am is just a tv show, but when I look at the take off scenes, when fire is coming out the engines of the 707s, I see that the engines are JT-4s. When EA-6bs would take off my old ship, there exhaust would turn fire orange, and think that is due to it having turbo jets. So did turbo jet powered 707s do the same thing?

Quoting 747400sp (thread starter), "So did turbo jet powered 707s do the same thing?"

J.D. that's a good question. I have watched that show exactly one time (don't intend to watch it again) and I was completely amazed at how inaccurate everything was with regard to airplanes, crews, airline operations, etc.

The only thing I ever saw coming out of those old engines was lots of "black smoke".

I'll have to take a closer look as it comes to BBC Two tomorrow night (first two episodes being shown and nice thing about the BBC is no adverts). Not being from that era, and having not seen a 707 take off before (certainly not one with turbojets either then!) it'll be interesting to see. I did know that a lot of those older aircraft had a hell of a lot of black smoke coming from them and I understand that one aircraft type (not sure which) caused some people to phone emergency services regularly thinking an aircraft was on fire or something because of the intensity of it.

Going of a TV show might not be all that accurate - even Air Crash Investigation had a blooper the other day (one with the A320 crash during a demonstration flight) on the diagram of the A320 it said "Turbojet" rather than "Turbofan". I also found it amusing when they reproduced the cabin of the BA 777 that landed at LHR a few years back with both engines gone, strangely reminiscent of a 70s/80s A300 interior...

That a/c, would be a Convair 880/990.

In the right low light and humidity conditions, I've seen B707 and DC-8 aircraft have a redish glow out the back of the engines on takeoff. I've even got some very old photo slides around here somewhere that show a JAL B747-100 doing the same thing on Guam. The interesting thing is that I did not notice a glow when I took the picture, only in the slide after it was developed.

I've not watched the TV show. But I'd suspect one writer or director or special effects designer once saw one picture of such an event, and puts the effect into every takeoff shot.

FWIW in WWII, the way to tell an ME262 strip from one with piston engines was the ME262 had concrete runways because the engines tended to set asphalt runways on fire. So the Alled fighters hung around the concrete strips to catch the ME262 when they were landing or taking off. Mind you those engines were about 30% more thirsty than the Nenes so the energy had to go somewhere.

I'm never amazed by how inaccurate TV shows are about anything.

Completely plausible. It's not uncommon to see the combustion chamber of modern turbofans glowing when it's dark outside and you're sitting at the right angle.

In the interests of science I took a look at episode 1 online. Looks like some TV art director got carried away with the CGI. They appear to have assumed the multi-lobe silencer is some kind of gas burner and that the various tubes lit up individually with blue flame. Just as bad, the cabin aisle looks about twice as wide as it should. On the plus side, the flightdeck set they've used looks quite realistic.

Except the takeoff shot referred too was in bright sunlight....

Who do you think pays for all those commercials you have to sit through? OK, you don't notice paying for them, but the cost is in the retail price of everything you buy. Give me advert free BBC any time, licence fee or not. PanAm episodes run for about 42 minutes in the UK, so that makes 18 minutes of ads I don't have to watch.

This might be for narrative purposes. In the West Wing TV show, the corridors were about twice as wide as in the actual West Wing. That way the characters could walk and talk.

Wide aisles and corridors are very common in films. There simply isn't enough room in a normal sized aircraft aisle for the staging/ blocking necessary to present the characters to interact with each other and the cameras and lighting.

The same with most normal building corridors.

Apparently they built a lifesize 707 set, in a hangar in Brooklyn Navy Yard. But it certainly looks like they've used panels from the real thing.

I suppose you need enough space for the film crew to move about, especially if it was shot in a full size cabin mockup. I suspect they wanted the cabin to look more spacious than it really was to convey the sense of luxury too. The flightdeck looks realistically cramped in comparison. The lighting was hyper real too, everything glows, in exactly the way a real aircraft interior doesn't.

It seems to me a big error in the opening series was that if this was based in the 1960s then the flight deck crew [for a trans atlatic flight] should have included a navigator, as INS only came in at the end of the 1960s

Ditto. As a precocious 8 year old, I loved watching those things taking off, and remember asking my father why there was no fire coming out of the engines. Ever. Lots and lots of really black smoke, and a hell of a lot of noise. My mother used to hang clothes out to dry, until the jets arrived at Idlewild. The soot in the landing pattern to 13r was pretty bad until the arrival of the 747s. The smoke, by the way, was apparently an excellent flight avoidance system for the pilots at altitude. (The TV series aircraft are way ahead of their time, smokeless at cruise) But alas, no fire, and when there was, it meant trouble. And speaking of errors, did the 707-100s have tail skids? I don't remember them until we got the real, intercontinental planes (-300s). Clipper Majestic seems to have one (along with 36"+ wide aisles).

If you mean did they have ventral fins, they didn't have them when new. Probably got them around 1961?

To my knowledge, Pan Am removed the navigator in the early/mid 1960's; before INS. Doppler and Loran were used, and Omega was phased in later. Pan Am 707's weren't equipped with INS except for N880PA which made the 25th anniversary flight in 1983. Can anyone confirm this?




I just want to know where all the CGI creators hid all of the DC-8's.

The original 707-121 were powered by JT3C-6 - (Water Injection)

That did increase the amount of black smoke out the back. And sounds quite cool.

Thanks for that but are you sure they only removed the specialist job, but carried an extra pilot instead. I ask this as BOAC in the late 1950s early 1960s also replaced straight Navs and replaced them with pilot /nav, and like you mentioned on the North Atlantic they used doppler and Loran along with other aids, but this information was then plotted onto a chart from which new heading info was given to the pilot on a bit of paper.

However different control authorities might have had different rules

Thanks again little vc10

Jan 30, 1974 - B707 Clipper 806 crashed short of the runway at Pago Pago American Samoa - NSTU / PPG - on a flight from ANZ - HNL - flight crew consisted of four people - a Captain, a First Officer, a Third Officer and a Flight Engineer. The Third Officer acted as co-pilot on the flight and the First Officer acted as Navigator while in the jump seat. The Third Officer was older than the First Officer and was initially a navigator with Pan Am who moved up to pilot when the specialist position was eliminated.

When I was on Guam in 1972-74, Pan Am B707 and B747 crews flying to the island were three pilots and a flight engineer. Many of the pilots were also originally navigators.

I believe Clipper Majestic was a 707 321 with JT4s.
