About me

I am Javier Irastorza Mediavilla, born and raised in Madrid (Spain) and currently living in Toulouse (France). I am a husband and father of a daughter and a son, aerospace engineer, MBA, marathoner, private pilot… and lucky enough to work in the quite vocational aerospace sector.

This is my personal blog (*), started in February 2010. The blog is mostly about aerospace & defence (26% of the posts), travelling (14%), sports (13%), books (9%), investing (7%) and economy (6%); these topics make up for three quarters of the entries (figures updated up to January 2019).

Yes, you may conclude that those are my passions.

When I reached the first 100 posts, I made a list with the most and least read ones of them, you may find the list here. I repeated the exercise after the first 200, 300400, 500 and 600 posts.

I want to complete this “About me” section with the link to my LinkedIn profile, so you can know more about my professional life and education.


(*) The opinions expressed by myself in the blog are my opinions, I do not speak for my employer, nor the associations and clubs I am engaged with, nor the organizations that I support. On the other hand, opinions expressed in the comments section by third persons are not necessarily shared by me.

    With regard to the 787 discourse, I wonder if the economies expected over time on the production of traditional metal aircraft are really possible with composite aircraft? Are shortcuts or efficiencies possible when working with these materials?

    I was just going through some finance related sites and blogs and came across your site https://theblogbyjavier.com/ too. I was impressed with vast array of valuable and unique information.

    I am working and associated with many finance and real estate sites as a content writer and I write articles on various topics of Finances, Real estate , Home. I was impressed the way you have presented your site. I propose you for a guest post writing on your site like I did for other sites without charging you a penny .

    The article will be 100% unique and will be published only on your site. If you want we can move further with this. If you have any topic in mind, please let me know and I will start working on that topic.

    Looking for your positive reply…:) 🙂



    • Hello, Britney,

      thanks for your words, and I’m glad that you liked the blog. Nevertheless, I started it as a personal blog where to write about anything that came to my mind and it will continue to be that personal refuge :-).

    hi javier
    can you please do a daily blog about boeing
    that would cover
    787 for Dummies
    747-8 for dummies
    737 max for dummies

    boeing for dummies

    • Hi Thomas,

      I appreciate your kind words and suggestions for future posts. However, I am not a professional blogger neither this is a professional blog. I use to write about several things that interest me or I do, some of them related to aerospace. I also come and write from time to time, and thus couldn’t produce a daily blog about Boeing.

      Regarding your ideas: for the 747-8 the data might be out there already, so it would only be a matter of compilation. For the 737 max I guess we don’t have yet as much info as I could gather for the 787 post.

    I read your blog post about about the Berkshire Hathaway Annual ShareHolder Meeting with interest.

    I am hoping to attend the 2013 meeting for the first time, but I had a query – is a 18 month old infant allowed at the events like the cocktail reception and NFM picnic, etc (though I realize, he will not be welcome at the actual Q&A meeting).

    I searched but could not find any info on this, so thought to ask you since you have been to the meeting.


    • Hi Atul,
      I believe we saw children when we attended in 2011. Nevertheless, I suggest you to contact Warren’s secretary (see contact in Warren’s letter to shareholders); in 2011 we contacted her (then was Debbie Bosanek, different one from now) both by email and phone and she was reachable, helpful and prompt in her answers.

    Thanks for your reply. I re-read the 2012 letter just now, but could not find her contact info. If you have it, could you please share it?

  6. Hey there, I think your site might be having browser compatibility issues.
    When I look at your blog site in Safari, it looks fine but when opening
    in Internet Explorer, it has some overlapping. I just
    wanted to give you a quick heads up! Other then that,
    amazing blog!

    I’m starting up my 2015 Marathon of Rotterdam project. I’ll ran it on my 60th birthday, so not on the official date. I ‘m interested in your experiences of Rotterdam 2014 for my blog. Can you send me your email for further information. Thanks.

    PS I found you googling Belayneh Dansamo

    Hi Javier, I stumbled upon your blog while searching for someone else who did the Wharton Introduction to Operations Management course as I cannot find my syllabus/course outline. I must say, nice blog. If you have the info I’m looking for, I’d appreciate you sending it to me. Thanks
