As a part of our test flight procedure for Operation IceBridge, we have to calibrate our instruments using a variety of aerial maneuvers. This is the DC-8 going into 90 +/- rolls. I'm betting you've never done this in a plane with four jet engines before. Enjoy!
NASA's Operation IceBridge images Earth's polar ice in unprecedented detail to better understand processes that connect the polar regions with the global climate system. IceBridge utilizes a highly specialized fleet of research aircraft and the most sophisticated suite of innovative science instruments ever assembled to characterize annual changes in thickness of sea ice, glaciers, and ice sheets. In addition, IceBridge collects critical data used to predict the response of earth's polar ice to climate change and resulting sea-level rise. IceBridge also helps bridge the gap in polar observations between NASA's ICESat satellite missions.

What always amazed me was how the engines were slung so far forward of the leading edge.Imagine the stress loads on that area of the pylon assembly.

@dragonmeddler2152 6 лет назад

Watched a KC-135 do a top speed flyby on the deck then climb nearly vertical to 10,000', kick over inverted, then roll right side up. Incredible sight I'll never forget.

@myZisfantastic 7 лет назад

Oh yes I did! DC8 French Air Force training, what we called"anusual positions". The instructor put the plane in a "very high nose attitude" and the trainee had to regain control of the ship! We practiced these exercices over the Alps with a beautiful scenery below us! Cheers

Interesting stuff, good to see this DC-8 still flying, worked on this plane for much of the 90's! Did some crazy shit back then too, flying thru the eye of typhoon "flo" (26.83 baro pressure), putting two engines in reverse(thrust) in flight! just to name a few. Good times they were.

Absolutely should be a part of every commercial airlines flight plan: "Ladies and gentlemen, the pilot has turned on the 90° roll sign. Please remain in your seats with your seatbelt fastened."

@davidhoffman5789 6 лет назад

Apparently some stories may be true. I think there was mention of a sudden decompression maneuver in a book a read a long time ago. If you just pushed over into a dive to get to a lower altitude people and stuff would go flying upward and get injured. The maneuver was to roll first to a few G loads, while also doing a 180 degree turn. That pinned the people to their seats. Once the passengers were pinned you went for the dive. You could continue to hold the higher than normal G loaded turn until you got below 14,000 Ft altitude or you could straighten out and descend in a straight line.

@bobbypaluga4346 6 лет назад

Sounds like a great ride on a simulator, but it's not exactly book as I understand it. Often a decompression weakens the aircraft structure, and your sure as hell not going to play around with aerobatics, delaying your return to dense air. Another factor in a few blowouts, is the loss of 1-2 engines which forces you to lose altitude because you cannot maintain 36-40,000 feet. The HNL-Auckland UNITED 747, cargo door event took at the 3 and 4, the PIC knew he could not hold above 15,000 feet. The floor was weakened as was the right side of the fuselage where a cargo door had been. I think most line pilots descent at what they feel to be the highest rate they can safety use. Whether it be 4,000-6,000 FP!M. Or even greater.

@davidhoffman5789 6 лет назад

Yes, both that 747 and the 737 that lost its top were significantly structurally compromised. In those cases the pilots might have to do some different procedures for descending. I was thinking more along the lines where you have a loss of one passenger window transparency , but not much more.

@gerardmoran9560 8 лет назад

Handled with the proper care, many transport jets can easily perform all sorts of maneuvers (sorry Airbus guys, the machine will intervene to stop you). Back in my USAF days, my last 3 years were in SpecOps and I knew the old C-141 could do more than realized. I flew a few flights with engineers from NASA, Lochkeed and the USAF all wired to multiple sensors. My crew and I demonstrated numerous maneuvers well outside the usual maneuver limitations, without exceeding any aircraft stress limitations. Big jets can be hamfisted into disaster or finessed into success depending on the experience of the crew.

Boeing's chief test pilot did a barrel roll during the 707's first flight. These planes are capable of remarkable things when they're not hauling hundreds of people from city to city.

@bobbypaluga4346 6 лет назад

Steven Cramsie Tex Johnson, in fact he made two. The aircraft was the Dash 50, a prototype of the 707-100. To my knowledge the boys in Long Beach never tried the same moves on an 8. The key is powering up first before you turn on a wingtip. Lovely sound

@jerryrufener9281 6 лет назад

The aircraft was the "367-80", known to everyone as the "dash 80". The model 367 was the the Air Forces C-97. Boeing called the aircraft the 367-80 supposedly to hide the real intent of the project. The dash 80 was the proof of concept for both the 707 and the KC-135 but not strictly speaking the prototype of either. The KC-135 was the Boeing model 717 - and, yes, that number was re-used. Tex Johnson rolled the dash 80 in 1955 over Lake Washington at the Gold Cup. This was most decidedly not the first flight.

Back in the 90's working for burbank aeronautical we faa flight tested our hush kits out of plant 42 in Palmdale ' during shutter stall tests over the pacific the faa guy rolled the aircraft 180 our test pilot took the controls from him and just managed to recover from inverted dive ' when the aircraft came back 2 hrs early we knew something was wrong ' it blew all the slot seals and nearly broke the back of the aircraft ' after mutch work and numerous inspections we got back in the air ' a 180 in a dc8 was a first as far as I know scary shit !

@bobbypaluga4346 6 лет назад

I wasn't aware of the 717 story, it does however explain why the 720 name was given the shorter range, fewer seats, 707 spawn. Tex Johnson's twin barrel rolls may have been the first flight seen by perspective buyers, certainly they had flight tested the Dash 80 at their remote fields such as Moses Lake. Dash 80 was more than a project name used during development, in the end Boeing went back to their long used numbering system and their is no reason to think they will abandon it in the future. Once 797 is breached, Boeing will start with 800's. Whether 801, or 807, even 811, we'll never know until they tell us.

@davidca96 4 года назад

@poly_hexamethyl 6 лет назад

So, when you fly on your side like that, do you lose a lot of altitude because the wings are no longer in a position to counteract gravity, or can you step on the rudder hard enough to keep flying level?

@jamesjacobson8050 6 лет назад

Yeah, you lose a lot of altitude. If you listen to the audio, you can hear the engines ramping up just before the roll in an effort to climb again before the drop.

@wotan10950 8 лет назад

I assume the engine run up before each maneuver is to gain speed and altitude before entering the high drag configuration?

@stevencramsie9172 8 лет назад

+Dave Glo More like the correct pitch as it's safer to go into a maneuver like this with the nose up. They are clearly already at a high enough altitude.

@elainefrantz9139 7 лет назад

Dave Glo You bet! Right on!

@Jdr1053 6 лет назад

Being in a knife edge doesn't increase drag so long as the maneuver is flown at low G, i.e: between 0 and 2G. Which in this instance is most likely the case as in transport category aircraft higher Gs are generally avoided. IMHO The increase in power here has more to do with the aircrew wanting to keep as much momentum on the up-slope in order for the nose not to come back down prematurely and/or excessively. Again to avoid having to get into recovery maneuvers causing higher G forces and increased drag, both of which could have the potential to over stress the airframe.
