Assembling a Boeing 737

An evening pause: I might have posted this before, but who cares. Modern engineering and smart production management is always nice to watch.

Hat tip Phill Oltmann.

Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.

The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

    Mr Z, how is the hat tip done on your site?

    The most produced modern airliner ever, great aircraft!
    It has been in production for over 50 years and still has orders.

    And disassembly of an aircraft. Rotting like a dead corpse in the African heat, to the benefit of the decomposers.

    LocalFluff, thought of this exact clip before I clicked the link!

    C Cecil–

    If I may– If you would like to submit suggestions for the evening-pause, just go to the ‘About’ page at this site, Mr. Z’s email address is at the bottom of the text.

    Use the Search-box in the right-hand column, to check if your suggested vids have already been posted in the past.

    If you ever get into the Seattle area, there is a nice tour of the Boeing manufacturing plant in Everett.

    There are several other aviation related museums, including the Museum of Flight and a Paul Allen collection of airplanes.

    The 737 is a great aircraft and is still wildly popular. Your link says that Boeing is ramping up production to 57 per month in hopes of clearing out the backlog of 4,400 orders. That is a six and a half year backlog.

    However, it is not the longest running production airplane. The C-130 was first flown in the mid 1950s, and the last I heard they are still building 6 per year. The C-130 is useful but not quite as popular as the 737.

  • C Cecil: I am not sure what you are asking. If you wish to donate or subscribe, there is a tip jar in the right column of my webpage. If you wish to contribute suggestions for an evening pause, say so here, and I will email you how to forward your suggestion to me. Do not post the link to your suggestion here, as I will then not be able to schedule it later.
