    It's a very interesting program. But the presenter reminds me of Sideshow Bob from The Simpsons. The hair, the suit, and the walk. But mostly the hilarious hair.

    And the boeing 747 isn't really 2 decks as the upper deck doesn't stretch through the entire aircraft, the a380, however, does

    CAN ANYONE TELL ME WHAT AN A-380 WAS?

    I heard that Airbus is refusing to repay Germany 1 billion Euros borrowed to develop the A-380, but I'm not sure what the A-380 was.

    Five week’s downtime for this overhaul? Like they say, a plane on the ground is a plane that’s losing money. Kudos to BA for putting safety ahead of profits for that particular aircraft.

    Documentaries like these make me appreciate the western white culture more and more. From the light bulb to the International Space station and everything in between is mostly the brainchild of the western civilization (with the exception of Japan). I sometimes feel that whites and the Japanese are superior compared to other races. There is nothing that they can achieve, I wish India could learn a thing or two instead of believing in superstition , i wish they do Math & Science more.

    Just been watching this very interesting and I really was fascinating to see the work
    Done on the 747 and every thing
    On the plane I have to say I have a
    Lot of respect for those engineers
    And everyone who services the cabin and the seats up to fuse large seats and the wings and engines undercarriage man what a
    Job for those guys with out them
    Planes would be falling out of the sky's so I give my life to them respect to them and the dislikes
    They should try and have an understanding of what they are
    Doing it just shows a lot of people
    Don't appreciate these engineers
    Doing my then an excellent job i
    Really enjoyed watching this so
    Much and a big massive thanks
    To you all peace and thankyou
    You tube for this very educational
    Video

    The 747 is the most wonderful/beautiful plane ever built. Period. My favorite memory in life, was sitting behind my dad(Captain) in the jumpseat taking off out of Rome and landing in Kennedy.

  • GARDEN OF EATEN TRUTH

    ISNT THE REASON FOR LIGHTNING STRIKES ENERGY JUMPING FROM POSITIVE TO NEGATIVE… MAYBE THE CRAFT SHOULD MATCH WHAT ITS FLYING IN.. MAYBE THE STATIC ANTENNA ARE NOT WORKING IN YOUR FAVOR… ISNT THE REAL REASON THAT WATER EVAPORATES BECAUSE THE NEGATIVE WATER IS ATTRACTED TO THE POSITIVE SKY… THEN ONCE THE WATER HANGS OUT IN THE SKY LONG ENOUGH IT BECOMES LIKE ITS ENVIRONMENT GIVING THE WATER A POSITIVE CHARGE AND THEREFORE IS ATTRACTED TO THE NEGATIVE GROUND.. SO IF WE APPLY THIS TO AIRCRAFT WE SHOULD BE ABLE TO ASCEND SIMPLY BY ADJUSTING OUR CHARGE… THE BOTTOM OF THE CRAFT IS NEGATIVE AND WILL PUSH AWAY FROM NEGATIVE EARTH INTO POSITIVE SKY.. EVERYTHING OPERATES OF THE PRINCIPLE OF MAGNETISM.. POSITIVE NEGETIVE… OR MALE AND FEMALE

    Did he say 2 million lbs the 747-400 weight is just over 400k lbs 2 mill that thing would need 26 engines

  • eth3rl0rds

    This is why brits get bumfuqed! Rather than admiring european pride airbus , they adore that garbage american engineering! Engineering marvel my a$$, in the end, it's just another mcdonald's …

  • Jo Mama

    19 Arab high jackers knew all about maintaining and flying machines
    like the one above !
    Allah is Akbar in real for them rats to know how to fly plains while they’re going five hundred miles an hour to get em through a pinhole !
    George bush and Rumsfeld alone with Dick Chaney taught em how to do it while some Israeli go go dancers were doing the honky tonk on the roof of their mothers brothel

  • chapmasi

    Although I prefer Flying on the A380 as objectively it is a newer and "better" plane….. The 747 was designed in an era without the technology we have now and it was a monumental game changer. Such an achievement. I really enjoyed watching this

  • Gimme Shelter

    This documentary is a good reminder to make the most of every BA 747-436 you see from now through to 2023 when our big girls finally leave the skies.

  • Gary Templemain

    Just the most interesting video. Bless you you all to protect us the flying public. I have lost count of the flights I have done over the years around thg world but it's expert technicians that give you the faith in Boeing

  • Matt Kiely

    I was a mechanic (L.A.M.E) for 30 + years. First up, the test flight after a D check (which normally involves a the Landing gear replacement/overhaul.) requires a Landing gear free fall test (alternate extension). One time on a test flight we had the RH wing gear not lock down, (or indicate it was not locked down) Everything would indicate normally when the hydraulic sys extension was done. So after the test flight we had to pull the aircraft back into the hangar and do a swing and check what was wrong. When we extended the gear, we had to push extra hard on the RH wing gear wheels as shown at 10:37 on the video, and then everything inicated "down and locked". Some extra lubrication was applied. Several days later after the aircraft was back flying, the QA department flagged it and wanted the aircraft pulled back into the hangar for positive rectification of the defect. We then found that the Hydraulic Extension Cylinder had high internal resistence friction and when we replaced that, the gear would easily lock into place after a free fall. Luckily I wasn't directly involved although I was on the test flight and wrote up the defect and was scolded by my senior for not telling the pilot to throw the aircraft around to "get the gear to lock down".

    I’m a private and envied your calm demeanor and willingness to share your flight plan. Excellent camera work. Thanks

  • David Bigar

    One takes off from my city to London every night at about 8pm as I watch it go I think someday I will be on that plane, so I have been saving for a first class flight next year. Can’t wait to see the 🇬🇧

  • Little Traveller

    This is a rare machine that just doesn’t seem to age. You see an airbus a380 and although much newer this design 40 odd years old still looks more pleasing.

  • Josh D

    really surprised how many manual tools are used in the process vs. pneumatic and electric tools. Also, it's ALUMINUM.

  • T G

    Those workers are not really engineers. They don't have real engineering degrees. It takes years of education with mathematics way past calculus to be a real engineer! They're only technicians. I think the company lets them call themselves "engineers" to make them feel important. This would be like calling the real engineers in the front offices designing the protocols "scientists". LOL

  • Joe Damm

    To the guy who posted the video. This is more of an MRO Heavy Maintenance "C Check". The "D Check" is more for Line Maintenance.

  • ゆうた

    The explanation of Bernouilli's principle is absolute bullshit. This is NOT how lift is generated. It's embarrassing to see this in a documentary. Do your homework or consult experts before you put false information out there.

  • Larry Easton

    As an A&P I completely relate to the feeling experienced when the ship you have worked on rotates on the take-off roll. Love my job!

    3 Fun facts about the Wright Brothers flyer plane:
    1. The elevators were at the front, aerofoil wings and rudders were at the back.
    2. The plane was made of giant spruce wood, sitka to be exact!
    3. The wooden propellers were hand carved, it was pusher-prop prop meaning the propeller was behind Wilbur and Orville and the Aluminium engine was painted black, with a weighted track/rail to launch the Wright Flyer.✈️✈️✈️
    Now we have jumbo 747's and A380's!✈️✈️✈️🛫🛬

  • Leon Greenfield

    A really fascinating documentary of the hugely complex work done on a Boeing 747-400
    D check ! Very interesting. The Boeing 747 is my all-time favorite aircraft ! Very many thanks for providing this excellent video

  • David Leonard

    Does anyone know if the front of the engine could be modified in such a way as to prevent birds from getting into the engine at all? A grate perhaps?

  • YoYO Semite

    That long haired dweeb ought to be made to wear a hair net while sticking his nose into precise cleaning areas, loose hair causes more problems.

  • Michael Tarasenkoop

    One of the best planes ever made and it should keep on being upgraded the best looking and most reliable for the number produced when it came out I flew on one it was unbelievable for it’s size !

  • Leander Williams

    5:38 time for the 200 million pounds worth of 747… That must be the heaviest plane ever devised by man… lol I think he meant 200 million pounds that it cost, not weighed. A Fully loaded 747 has a maximum takeoff weight of about 875,000 pounds.

  • roasthunter

    Nice, I'm watching this 7 years since this video was publish so one assumes it's had another D check since and is still in service with BA. It currently over Cameroon flying from South Africa to London as I write this.

  • Pat Rick

    JDProductions INC. Exactly what is "aluminium"? … Is it something like "aluminum"? Is it lighter than Aluminum or is a new metal? I don't get it!

  • gmrb79s

    "IM AN ENGINEER" blah blah… fucking get technical then… any kid wouldve made this documentary a lot more interesting with ELI5 questions…

  • D Stuart

    People with massive responsibility are massively sexy. Let's pay for the r and d to make them truly carbon neutral–then they will truly be marvels. Of course Tories and Republicans hate regulations that require a lot of these safety checks. They also want food inspection regulations reduced.

  • DJ Roper

    Sad to see it go from our skies. Beautiful aircraft. Superior looking to A380 and the latest long haul planes like the 787 and a350 series.

  • Bruno Silva

    "Is it true that when there's two pilots on board, they have to have a different meal?"
    Like sometimes there's only one pilot on board…
